The molecular components of the title salt, [Cu(C4H11NO2)2](C8H4O4), are one CuIIcationO,N,O′-chelated by two tridentate 2-[(2-hydroxyethyl)amino]ethanol ligands, and a terephthalate counter-dianion, located about a centre of inversion. The complex CuIIcation is located about a centre of inversion and shows typical Jahn–Teller distortion, with two short Cu—O and two short Cu—N bonds in the equatorial plane and two long Cu—O bonds to the axial atoms. The cations are arranged in sheets parallel to (100), with the centrosymmetric terephthalate anions located between the sheets. Each anion is the acceptor of four O—H...O and two N—H...O hydrogen bonds, forming a three-dimensional network structure.

In the crystal structure of the title compound, [Sn(C42H26N6)(C7H5O2)2], the SnIV ion is located on a crystallographic inversion centre and is octahedrally coordinated with an N4O2 set. Four N atoms of the porphyrin ring form the equatorial plane while the axial positions are occupied by two O atoms from benzoate anions. The molecular packing of the title complex involves non-classical hydrogen bonds of the types C—H...O and C—H...N, leading to a three-dimensional network structure.

The crystal structures of the first-row transition-metal series of tris(ethylenediamine-κ2 N,N′)metal(II) diacetate, [M(C2H8N2)3](CH3CO2)2, with M = Mn, Fe, Co, Ni, Cu, and Zn, are reported. The complexes are all isostructural, crystallizing in a centrosymmetric triclinic cell and possessing an asymmetric unit composed of one [M(en)3]2+ cation and two symmetrically independent acetate anions. In the unit cell, the two complex cations are inversion-generated enantiomers, possessing the energetically favoured Δ(λλλ) and Λ(δδδ) configurations. The complex cations and acetate anions combine through a series of N—H...O hydrogen bonds to generate a three-dimensional network in the crystals. The other notable feature of the series is a significant Jahn–Teller distortion for the d 9 Cu2+ complex.

In the structure of the brucinium salt of 4-aminophenylarsonic acid (p-arsanilic acid), systematically 2,3-dimethoxy-10-oxostrychnidinium 4-aminophenylarsonate tetrahydrate, (C23H27N2O4)[As(C6H7N)O2(OH)]·4H2O, the brucinium cations form the characteristic undulating and overlapping head-to-tail layered brucine substructures packed along [010]. The arsanilate anions and the water molecules of solvation are accommodated between the layers and are linked to them through a primary cation N—H...O(anion) hydrogen bond, as well as through water O—H...O hydrogen bonds to brucinium and arsanilate ions as well as bridging water O-atom acceptors, giving an overall three-dimensional network structure.

The cation of the complex title salt, [Zn(C13H11N3)2(H2O)](NO3)2, lies about a twofold rotation axis, which passes through the ZnIIatom and the O atom of the aqua ligand. The ZnIIatom adopts a distorted trigonal–bipyramidal geometry defined by two N atoms in axial positions [angle = 166.24 (7)°], and two N and one O atom in the equatorial plane [range of angles: 115.17 (7)–122.42 (3)°]. The dihedral angle between the imidazole and aniline rings is 23.86 (5)°. In the crystal, N—H...O and O—H...O hydrogen bonds link the components into a three-dimensional network.

AbstractDuftite, PbCu(AsO4)(OH) is orthorhombic, space group P212121 with a = 7.768(1), b = 9. 211(1), c = 5.999(1) Å, Z = 4; the structure has been refined to R = 4.6% and Rw = 6.5% using 640 observed reflections [F> 2σ(F)]. The structure consists of chains of edge-sharing CuO6 ‘octahedra’, parallel to c; which are linked via AsO4 tetrahedra and Pb atoms in distorted square antiprismatic co-ordination to form a three dimensional network. The CuO6 ‘octahedra’ show Jahn-Teller distortion with the elongation running approximately along <627>. The hydrogen bonding network in the structure was characterized using bond valence calculations. ‘β-duftite’ is an intermediate in the duftite-conichalcite series, which has a modulated structure based on the intergrowth of the two structures in domains of approximately 50 Å. The origin of the modulation is thought to be associated with displacements in the oxygen lattice and is related to the orientation of the Jahn-Teller distortion of CuO6 ‘octahedra’. Approximately half of the strips show an elongation parallel to <627> while the other strips are elongated parallel to [010]. This ordering results in an increase in the b cell repeat compared to duftite and conichalcite.

The asymmetric unit of the organic–inorganic title salt, (C10H28N4)[Cr2O7]2, comprises one half of an 1,4-bis(3-ammoniopropyl)piperazinediium cation (the other half being generated by the application of inversion symmetry) and a dichromate anion. The piperazine ring of the cation adopts a chair conformation, and the two CrO4tetrahedra of the anion are in an almost eclipsed conformation. In the crystal, the cations and anions form a layered arrangement parallel to (001). N—H...O hydrogen bonds between the cations and anions and additional C—H...O interactions lead to the formation of a three-dimensional network structure.

Reaction ofm-aminobenzoic acid (MABA), diethanolamine (DEA) and MnCl2·4H2O led to the formation of the title salt, [Mn(C4H11NO2)2](C7H6NO2)2. In the complex cation, the Mn2+ion is located on an inversion centre and is coordinated by two symmetry-related tridentate DEA molecules, leading to the formation of a slightly distorted MnN2O4octahedron. The MABA−counter-anions are connected to the complex ion by a pair of rather strong O—H...O hydrogen bonds, yielding a 1:2 supramolecular aggregate. Much weaker N—H...O hydrogen bonds connect neighbouring aggregates into a three-dimensional network structure.

The crystal structure of the title salt, [Cu(ClO4)(C8H20N4)]ClO4, is reported. The CuIIion exhibits a square-pyramidal geometry and is coordinated by the four N atoms of the neutral 1,4,7,10-tetraazacyclododecane (cyclen) ligand and an O atom from one perchlorate anion, with the second perchlorate ion hydrogen-bonded to one of the amine N atoms of the cyclen ligand. Additional N—H...O hydrogen bonds between the amine H atoms and the coordinating and non-coordinating perchlorate groups create a three-dimensional network structure. Crystals were grown from a concentrated methanol solution at ambient temperature, resulting in no co-crystallization of solvent.

In the structure of the title salt, (C5H14N3)2[CuCl4], the CuIIatom in the anion lies on a twofold rotation axis. The tetrachloridocuprate(II) anion adopts a flattened tetrahedral coordination environment and interacts electrostatically with the tetramethylguanidinium cation. The crystal packing is additionally consolidated through N—H...Cl and C—H...Cl hydrogen bonds, resulting in a three-dimensional network structure.

In the cation of the title salt, C30H28NO2 +·CF3O3S−, the four tetrahydrofuran rings adopt envelope conformations. In the crystal, pairs of cations are linked by dimeric C—H...O hydrogen bonds, forming two R 2 2(6) ring motifs parallel to the (001) plane. The cations and anions are connected by further C—H...O hydrogen bonds, forming a three-dimensional network structure. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H...H (47.6%), C...H/H...C (20.6%), O...H/H...O (18.0%) and F...H/H...F (9.9%) interactions.
