Amine Function

In the title compound, [Cu(C9H6N3O2)2(C2H7N)2], the Cu2+ cation is situated on an inversion center and is coordinated by the N atoms of two dimethylamine ligands and the carboxylate O atoms of two 4-(1,2,4-triazol-1-yl)benzoate anions, leading to a slightly distorted square-planar N2O2 coordination environment. In the crystal, intermolecular N—H...N hydrogen bonds between the amine function and the central N atom of the triazole ring lead to the formation of ribbons parallel to [1\overline{1}1]. Weak intermolecular C—H...O hydrogen-bonding interactions are also observed that consolidate the crystal packing.

The structure of the title compound, [Cu4(CH3O)4(C11H13O2)4], consists of dimeric dinuclear copper(II) complexes oriented around a centre of inversion. Within each dinuclear fragment, the two CuIIatoms are in a distorted square-planar coordination sphere. Two neighbouring fragments are linked by four apical Cu—O contacts, yielding an overall square-pyramidal coordination environment for each of the four CuIIatoms. The molecules are arranged in layers parallel to (101). Non-classical C—H...O hydrogen-bonding interactions are observed between the layers.

The molecular structure of the title complex, [Ni(C13H8F2N2O)(C14H32P2)] or Ni(oFPU)(dippe), where oFPU is the dianion of bis(2-fluorophenyl)urea and dippe is 1,2-bis(di-isopropylphosphino)ethane, comprises an NiII atom with a distorted square-planar coordination environment (geometry index τ4 = 0.195). One of the fluorophenyl rings of the oFPU ligand is disordered over two sets of sites in an 0.832 (7):0.168 (7) ratio. The crystal structure displays C—H...O and C—H...F hydrogen-bonding interactions, leading to chains with R 2 2(12) motifs extending parallel to [100]. The title compound might be of interest with respect to the production of urea and carbamate derivatives of nickel(II).

The title compound, C18H20ClN3S, is a functionalized triazoline-3-thione derivative. The benzene ring is almost perpendicular to the planar 1,2,4-triazole ring [maximum deviation = 0.007 (1) Å] with a dihedral angle of 89.61 (5)° between them and there is an adamantane substituent at the 3-position of the triazolethione ring. In the crystal, N—H...S hydrogen-bonding interactions link the molecules into chains extending along thec-axis direction. The crystal packing is further stabilized by weak C—H...π interactions that link adjacent chains into a two-dimensional structure in thebcplane. The crystal studied was an inversion twin with a 0.50 (3):0.50 (3) domain ratio.

In the title compound, (C6H8N4)[AuCl4]Cl, the 4,4′-bi(1H-pyrazol-2-ium) dication, denoted [H2bpz]2+, is situated across a centre of inversion, the [AuCl4]−anion lies across a twofold axis passing through Cl—Au—Cl, and the Cl−anion resides on a twofold axis. Conventional N—H...Cl hydrogen bonding [N...Cl = 3.109 (3) and 3.127 (3) Å, and N—H...Cl = 151 and 155°] between [H2bpz]2+cations (square-planar node) and chloride anions (tetrahedral node), as complementary donors and acceptors of four hydrogen bonds, leads to a three-dimensional binodal four-connected framework with cooperite topology (three-letter notation pts). The framework contains channels along thecaxis housing one-dimensional stacks of square-planar [AuCl4]−anions [Au—Cl = 2.2895 (10)–2.2903 (16) Å; interanion Au...Cl contact = 3.489 (2) Å], which are excluded from primary hydrogen bonding with the [H2bpz]2+tectons.

The title compound, [PdCl2(C28H24N2)]·CH3OH, was prepared from the reaction of PdCl2(DMSO)2(DMSO is dimethyl sulfoxide) andN,N′-bis(4-methylphenyl)-1,2-diphenylethane-1,2-diimine in methanol. The chelating diimine core of the title compound deviates slightly from planarity, with an N—C—C—N torsion angle of 5.3 (3)°. Delocalization in the diimine core is indicated by N—C and C—C bonds that are, respectively, longer and shorter than those found in related nonchelating diimines. The distorted square-planar coordination environment around the PdIIatom is manifested as bond angles that are smaller and larger than 90°, and palladacycle torsion angles of −173.22 (16) and 167.06 (16)°. These deviations are attributed to the small bite angle of 79.13 (8)° of the diimine chelate. The crystal packing exhibits weak intermolecular hydrogen-bonding interactions involving aromatic H atoms, Cl atoms and intercalated methanol solvent molecules, defining layers parallel to (010).

In the centrosymmetric dinuclear title compound, [Pd2(C4H7)2(C16H14N2S2)], the metal atom is η3-coordinated by three C atoms of a crotyl ligand [Pd—C = 2.147 (4), 2.079 (5) and 2.098 (5) Å], the longest distance influenced by the steric interaction with the benzyl substituents of the dibenzyldithiooximidate (DTO) ligand. The Pd—N and Pd—S bonds to this ligand are 2.080 (3) and 2.3148 (9) Å, respectively, completing a square-planar coordination environment for PdII. The benzyl groups are oriented so as to maximize the interaction between a benzylic H atom and an S atom, resulting in a dihedral angle of 77.1 (2)° between the benzene rings and the metal complex plane. In the crystal, no inter-complex hydrogen-bonding interactions are present.

The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2core [Cu...Cu distance = 2.7482 (11) Å], the CuIatoms of which are further coordinated by four molecules of acetonitrile. The CuIatom has an overall distorted tetrahedral coordination environment evidenced byL—Cu—Langles (L= N or I) ranging from 100.47 (10) to 117.06 (2)°. The coordination geometries of the acetonitrile ligands deviate slightly from linearity as shown by Cu—N—C angles of 167.0 (2) and 172.7 (2)°. In the crystal, there are no significant hydrogen-bonding interactions present, so the crystal packing seems to be formed predominantly by van der Waals forces.
