Dibut-yl{N'-[1-(5-chloro-2-oxidophenyl-κO)ethyl-idene]-3-hy-droxy-2-naphtho-hydrazidato-κN',O}tin(IV).

ABSTRACT: The five-coordinate Sn(IV) atoms in the two crystallographically independent mol-ecules of the title compound, [Sn(C(4)H(9))(2)(C(19)H(13)ClN(2)O(3))], are in distorted cis-C(2)NO(2)Sn trigonal-bipyramidal coordination environments. The tridentate dianion of the Schiff base, N'-[1-(5-chloro-2-oxidophen-yl)ethyl-idene]-3-hy-droxy-2-naphtho-hydrazide, displays inter-molecular O-H⋯N hydrogen bonding, which stabilizes the overall compound.

(Acetyl-acetone 3-hy-droxy-2-naphtho-yl-hydrazonato-κO,N',O')(methoxo-κO)oxidovanadate(V).

Project description:The tridentate Schiff base ligand in the title compound, [V(C(16)H(14)N(2)O(3))(CH(3)O)O], has its O, N and O' atoms spanning three basal positions of the square-based-pyrimidally V(V) atom. The fourth basal site is occupied by a methoxo ligand, which results from a deprotonated methanol solvent molecule, and the oxido ligand occupies the apical position. The hy-droxy H atom forms an intra-molecular O-H⋯N hydrogen bond with an N-atom acceptor site.

Bis(μ-3-hy-droxy-benzoato)-κO,O:O;κO:O,O-bis-[(3-hy-droxy-benzoato-κO,O')(iso-nicotinamide-κN)cadmium] tetra-hydrate.

Project description:In the title centrosymmetric binuclear Cd(II) compound, [Cd(2)(C(7)H(5)O(3))(4)(C(6)H(6)N(2)O)(2)]·4H(2)O, the six-coordinated Cd(II) atom is chelated by the carboxyl-ate groups of the two 3-hy-droxy-benzoate (HB) anions; the two monomeric units are bridged through the two O atoms of the two carboxyl-ate groups. In the crystal, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π Contacts between the pyridine rings and between the benzene rings [centroid-centroid distances = 3.770 (1), 3.769 (1) and 3.632 (1) Å] may further stabilize the structure.

Diaqua-bis-(2-hy-droxy-benzoato-κO (1))bis-(nicotinamide-κN (1))cadmium-diaqua-bis-(2-hy-droxy-benzoato-κ(2) O (1),O (1'))(nico-tin-amide-κN)cadmium-water (1/2/4).

Project description:The crystal structure of the title compound, [Cd(C7H5O3)2(C6H6NO)2(H2O)2]·2[Cd(C7H5O3)2(C6H6NO)(H2O)2]·4H2O, consists of two kinds of Cd(II) complexes (A and B) and lattice water mol-ecules. In complex A, [Cd(C7H5O3)2(C6H6NO)2(H2O)2], the Cd(II) cation is located on an inversion center and is coordinated by two salicylate anions, two nicotinamide (NA) ligands and two water mol-ecules in a slightly distorted octa-hedral geometry. In complex B, [Cd(C7H5O3)2(C6H6NO)(H2O)2], the Cd(II) cation is coordinated by two salicylate anions, one nicotinamide (NA) ligand and two water mol-ecules in an irregular seven-coordinate geometry. There are extensive intra-molecular O-H⋯O and weak C-H⋯O hydrogen bonds as well as extensive inter-molecular O-H⋯O and N-H⋯O hydrogen bonding in the crystal structure. π-π stacking between the pyridine and benzene rings, between the benzene rings, between the benzene and pyridine rings and between the pyridine rings [centroid-centroid distances = 3.5989 (10), 3.6005 (10), 3.5800 (9) and 3.5205 (10) Å, respectively] further stabilize the crystal structure. A weak N-H⋯π inter-action also occurs. One of the lattice water mol-ecules is disordered over two positions with an occupancy ratio of 0.70:0.30.

Hydrogen bonding between hy-droxy H and carboxyl-ate O atoms results in a layer structure parallel to the ab plane.

(2-Hy-droxy-acetato-κO)bis-(1,10-phenan-throline-κN,N')copper(II) nitrate.

Project description:In the title compound, [Cu(C(2)H(3)O(3))(C(12)H(8)N(2))(2)]NO(3), the Cu(II) atom is coordinated by two phenanthroline (phen) ligands and one carboxyl-O atom of a hy-droxy-acetate anion in a distorted square-pyramidal geometry. The hy-droxy group of the hy-droxy-acetate ligand links with the counter NO(3) (-) anion via a pair of bifurcated O-H⋯O hydrogen bonds. The centroid-centroid distance of 3.5676 (14) Å between benzene rings of parallel phen ligands of adjacent mol-ecules suggests the existence of π-π stacking. Weak inter-molecular C-H⋯O hydrogen bonding is also present in the crystal structure.
