In the title compound, [Ni(C13H17N3)2]Cl2·3.5H2O, the geometry of the NiN6complex cation is slightly distorted octahedral, with a facial arrangement of the two tridentateN-[2-(dimethylamino)ethyl]quinolin-8-amine ligands around the metal ion. The asymmetric unit consists of two independent complex half-molecules located on centres of inversion, together with two chloride counter-anions and 3.5 water molecules of solvation, one of which is disordered across an inversion centre. In the crystal, O—H...O, O—H...Cl and N—H...Cl hydrogen-bonding interactions form a three-dimensional network structure.

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

The asymmetric unit of the title compound, [Cr(C2O4)(C10H24N4)]2[Cr2O7]·8H2O (C10H24N4= 1,4,8,11-tetraazacyclotetradecane, cyclam; C2O4= oxalate, ox) contains one [Cr(ox)(cyclam)]+cation, one half of a dichromate anion that lies about an inversion centre so that the bridging O atom is equally disordered over two positions, and four water molecules. The terminal O atoms of the dichromate anion are also disordered over two positions with a refined occupancy ratio 0.586 (6):0.414 (6). The CrIIIion is coordinated by the four N atoms of the cyclam ligand and one bidentate oxalato ligand in acisarrangement, resulting in a distorted octahedral geometry. The Cr—N(cyclam) bond lengths are in the range 2.069 (2)–2.086 (2) Å, while the average Cr—O(ox) bond length is 1.936 Å. The macrocyclic cyclam moiety adopts thecis-V conformation. The dichromate anion has a staggered conformation. The crystal structure is stabilized by intermolecular hydrogen bonds involving the cyclam N—H groups and water O—H groups as donors, and the O atoms of oxalate ligand, water molecules and the Cr2O72−anion as acceptors, giving rise to a three-dimensional network.

In the title salt, [Eu(C3H7NO)8][PMo12O40], the asymmetric unit comprises one α-Keggin-type [PMo12O40]3−polyoxidometalate anion and one distorted dodecahedral [Eu(C3H7NO)8]3+complex cation. In the crystal, the isolated polyoxidometalate anions are packed into hexagonally arranged rows extending parallel to [001]. The complex cations are situated between the rows and are linked to the neighbouring anions through weak C—H...O hydrogen-bonding interactions, leading to the formation of a three-dimensional network structure.

The asymmetric unit of the title compound, [Mn(C7H4BrO2)(C12H8N2)2(H2O)](C7H4BrO2)·2H2O, consists of a monovalent [Mn(C7H4BrO2)(C12H8N2)2(H2O)]+complex cation, a 4-bromobenzoate anion and two lattice water molecules. In the complex cation, the MnIIatom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands and two O atoms, one from a 4-bromobenzoate anion and the other from a coordinating water molecule. This completes an MnN4O2coordination sphere with a distorted octahedral geometry. The Br atom of the bromobenzoato ligand is equally disordered over two sites. In the crystal, the complex cations are connected to each otherviaO—H...O, O—H...Br and C—H...O hydrogen bonds and π–π stacking interactions [closest separation = 3.492 (4) Å]. π–π contacts [closest separation = 3.771 (4) Å] also link the complex cations to both the coordinated and non-coordinating 4-bromobenzoate anions. Overall, these contacts generate a three-dimensional network structure.

In the crystal, a combination of C—H...N and C—H...Cl hydrogen-bonding interactions connect the molecules into a three-dimensional network.

A novel polyoxomolybdate with a diprotonated porphyrin as counter-cation, namely, 5,10,15,20-tetrakis(4-carboxyphenyl)-21H,22H,23H,24H-porphine(2+) hexamolybdate(VI) pentahydrate, (C48H32N4O8)[Mo6O19]·5H2O or (H2TCPP)[Mo6O19]·5H2O, I, was prepared via the hydrothermal reaction of MoCl5, 5,10,15,20-tetrakis(4-carboxyphenyl)-21H,23H-porphine (TCPP) and distilled water. The crystal structure of hydrated polyoxometalate (POM) salt I was characterized by single-crystal X-ray diffraction. The compound is characterized by an isolated (zero-dimensional, 0D) structure, because it cannot extend via covalent bonds. The structure contains one [Mo6O19]2− anion, one (H2TCPP)2+ cation and five lattice water molecules. Each of the Mo6+ ions is six-coordinated and displays a distorted octahedral motif. The (H2TCPP)2+ cation displays a distorted saddle motif. A three-dimensional (3D) supramolecular framework is formed via hydrogen-bonding interactions. The compound shows a red photoluminescence emission.

The polymeric title compound, {[Co(C15H9NO4S)(H2O)3]·H2O}n, consists of chains along [001] made up from Co2+ions bridged by 10-methylphenothiazine-3,7-dicarboxylate anions. The Co2+ion, coordinated by three O atoms from two different carboxylate groups and three water molecules, displays a distorted octahedral environment. In the crystal, π–π interchain interactions, with centroid–centroid distances of 3.656 (2) and 3.669 (2) Å between the benzene rings of the ligands, assemble the chains into sheets parallel to (100). O—H...O hydrogen-bonding interactions between the coordinating water molecules and carboxylate O atoms link the sheets into a three-dimensional network.

The complex cation of the title compound, [Co(CO3)(C10H8N2)2]2(C12H10N2O6)·6H2O, contains a CoIIIatom with a distorted octahedral coordination environment formed by four N atoms from two bidentate 2,2′-bipyridine ligands and one bidentate carbonate anion. The asymmetric unit is completed by one-half of the 2-({4-[(carboxylatomethyl)carbamoyl]phenyl}formamido)acetate dianion, which is located on a centre of inversion, and by three water molecules. Two [Co(CO3)(C10H8N2)2]+cations are connected through C—H...O contacts by the uncoordinating anions. The aromatic rings of the 2,2′-bipyridine ligands and diacetate anions are involved in π–π stacking and C—H...π interactions. The centroid–centroid distances are in the range 3.4898 (4)–3.6384 (5) Å. The crystal structure is stabilized by further O—H...O and N—H...O hydrogen bonds, which give rise to a three-dimensional supramolecular network.
