The compound, {6,6′-dimethoxy-2,2′-[(4-azaheptane-1,7-diyl)bis(nitrilomethanylidyne)]diphenolato}zinc(II) methanol monosolvate, [Zn(C22H27N3O4)]·CH3OH, at 298 K crystallizes in the orthorhombic space group Pna21. The Zn atom is coordinated by a pentadentate Schiff base ligand in a distorted trigonal–bipyramidal N3O2 geometry. The equatorial plane is formed by the two phenolic O and one amine N atom. The axial positions are occupied by two amine N atoms. The distorted bipyramidal geometry is also supported by the trigonality index (τ), which is found to be 0.85 for the molecule. In the crystal, methanol solvent molecule is connected to the complex molecule by an O—H...O hydrogen bond and the complex molecules are connected by weak supramolecular interactions, so achiral molecules generate a chiral crystal. The Hirshfeld surface analysis suggests that H...H contacts account for the largest percentage of all interactions.

The title complex, [Sn(C6H5)3(C6H3ClNO2)(H2O)], is five-coordinate with a distorted trigonal–bipyramidal geometry in the solid state. The O atom of the carboxylate group occupies one of the axial sites and the O atom of the water molecule occupies the other. Water H atoms are involved in an intermolecular hydrogen-bonded network with the uncoordinated carboxylate O atom and the pyridine N atom; the interactions lead to two types of rings.

Abstract The title compounds [R2NH2][C2O4SnMe3](R=i-Bu, Cy), in which tin atoms adopt a distorted trigonal bipyramidal configuration, have been prepared and submitted to an X-ray diffraction study. These compounds have been obtained from the reaction of (Cy2NH2)2C2O4·H2O or (i-Bu2NH2)2C2O4 with SnMe3Cl. In both [R2NH2][C2O4SnMe3] compounds, the trans complex has an almost regular trigonal bipyramidal geometry around the tin atom. The SnMe3 residues are connected as a chain with bridging oxalate anions in a trans-SnC3O2 framework, the oxygen atoms being in axial positions. The cations connect linear adjacent chains through NH…O hydrogen bonds giving layered structures.

The coordination environment of the zinc(II) ion in the title complex, [ZnCl2(C22H14N4)], is distorted trigonal–bipyramidal comprised by three N atoms from the 2-([2,2′-bipyridin]-6-yl)benzo[b][1,5]naphthyridine ligand and two Cl−ions. In the crystal, neighbouring molecules are connected by π–π stacking interactions along thea-axis direction.

The mixed-valence μ-oxide Sn12cluster, decacarbonyltetra-μ4-oxido-hexa-μ3-oxido-tetrakis[μ-2,2′-(pyridine-2,6-diyl)bis(1,1-diphenylethanolato)]decatin(II)ditin(IV)dimolybdenum(O)(2Mo—Sn) toluene heptasolvate, [Mo2Sn12(C33H27NO2)4O10(CO)10]·7C7H8, has a crystallographically imposed inversion centre. The asymmetric unit also contains three and a half toluene solvent molecules, one of which is disordered about a centre of symmetry. The complex molecule comprises six distinct Sn atom species with four different coordination numbers, namely 3, 4, 5, and 6. The SnIIatoms forming the central Sn10O10core adopt distorted trigonal–pyramidal, square-pyramidal and octahedral coordination geometries provided by the μ-oxide atoms and by the O- and N-donor atoms of two pyridinediethanolate ligands. The terminal SnIVatoms have distorted trigonal–bipyramidal coordination geometries, with a μ4-oxide atom and the N atom of a pyridinediethanolate ligand occupying the axial positions, and the Mo atom of a Mo(CO)5group and the alkoxy O atoms of a ligand forming the equatorial plane. In the crystal, weak intra- and intermolecular C—H...O hydrogen bonds are observed.

In the mononuclear title complex, [CdBr2(C20H17N3)(C3H7NO)], synthesized from the quinoline-derived Schiff base 2-(1H-indol-3-yl)-N-(quinolin-2-ylmethylene)ethanamine (IQME), the coordination geometry around the Cd2+atom is distorted trigonal bipyramidal, the axial positions being occupied by the quinoline N atom [Cd—N = 2.401 (3) Å] and one dimethylformamide O-atom donor [Cd—O = 2.399 (2) Å]. The equatorial plane is formed by the imine N atom [Cd—N = 2.293 (3) Å] and two bromides [Cd—Br = 2.5621 (8) and 2.5676 (8) Å], with the deviation of the CdIIatom from the equatorial plane being 0.046 (1) Å. An intramolecular C—H...Br interaction occurs. In the crystal, N—H...Br interactions generate [101] chains.

The preparation and physical properties of octahedral and trigonal bipyramidal complexes incorporating the tris-chelating ligands [Me2Ga(N2C5H7)(OCH2CH2NR′2)]− (R′ = H or Me) are described. Crystals of [dimethylbis(3,5-dimethyl-1-pyrazolyl)gallato (N(2),N′(2))][dimethyl (3,5 - dimethyl-1-pyrazolyl) (N,N-dimethylethanolamino(gallato (N(2), O, N(3))]nickel(II) are triclinic, a = 20.8562(11), b = 9.1536(4), c = 8.2798(4) Å, α = 100.204(3), β = 85.513(4), γ = 101.989(3)°, Z = 2, space group [Formula: see text]. The structure was solved by Patterson and Fourier syntheses and was refined by full-matrix least-squares procedures to R = 0.048 and Rw = 0.078 for 5508 reflections with I ≥ 3σ(I). The coordination about the Ni atom is distorted trigonal bipyramidal with the two nitrogen atoms from the Me2Ga(N2C5H7)2 ligand occupying equatorial positions. The tridentate Me2Ga(N2C5H7)(OCH2CH2NMe2) ligand is meridionally coordinated with the oxygen in the equatorial and the two nitrogens in the axial positions. Important bond lengths (corrected for libration) are: Ni—N(eq), 2.005(3) and 2.006(3), Ni—O, 1.993(3), Ni—N(pz—ax), 2.072(3), Ni—N(amino), 2.229(3), Ga—O, 1.913(3), Ga—N, 1.971(3)–1.989(3), and Ga—C, 1.961(10)–1.986(6) Å.
