ABSTRACT: The Cu(II) ion in the title complex, [Cu(C(15)H(12)N(2)O(3))(C(4)H(9)NO)], is coordinated by one carbonyl O atom, one hydrazine N atom and one phenolate O atom from the doubly deprotonated tridentate ligand and one N atom from a morpholine mol-ecule, forming a distorted trans-CuN(2)O(2) square-planar coordination geometry. An intra-molecular O-H⋯N hydrogen bond occurs within the ligand, generating an S(6) ring.
Project description:In the title compound, [Sn(C(6)H(11))(2)(C(19)H(14)N(2)O(3))], the Sn(IV) atom is O,N,O' chelated by the deprotonated Schiff base ligand and exists in a cis-trigonal-bipyramidal environment, completed by the two cyclohexyl ligands.
Project description:In the title compound, [Cu(2)(C(15)H(12)N(2)O(4))(2)(C(6)H(5)N)(2)], each Cu(II) atom is chelated by the tridentate doubly deprotonated Schiff base and a pyridine mol-ecule in a nearly planar environment (r.m.s. deviation for all non-H atoms = 0.107?Å). The metal ions are bridged by one O atom from the symmetry-related Schiff base ligands, forming a centrosymmetric dinuclear copper(II) complex. The dimeric complex is linked to another dimer via weaker Cu-O inter-actions and also O-H?N hydrogen bonds.
Project description:The metal atom in the title compound, [Cd(C(15)H(13)N(2)O(4))(2)]·2C(2)H(6)OS, is twice O,N,O'-chelated by two symmetry-related Schiff base ligands to define a trans-N(2)O(4) octa-hedral geometry. Each anion occupies meridional sites of the octa-hedron; the metal atom lies on a special position of site symmetry 2. The dimethyl sulfoxide mol-ecule is a hydrogen-bond acceptor to the -NH- unit, and O-H?O hydrogen bonds link mol-ecules into a supra-molecular chain.
Project description:The two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(16)N(2)O(3)S, are each linked by an N-H?O(sulfon-yl) hydrogen bond into a linear chain that runs along the shortest axis of the triclinic unit cell. The hydr-oxy groups are engaged in intra-molecular hydrogen bonding and the amino N atom shows pyramidal coordination.
Project description:In the title complex, [Ni(C(14)H(12)N(3)O)(2)], the Ni(II) atom lies at the centre of a distorted octahedron formed by two tridentate hydrazone ligands. Inter-molecular hydrogen bonds of the type C-H?X (X = N, O) link the complexes into a two-dimensional network.
Project description:The title complex, [Ni(C(15)H(10)BrClN(2)O(2))(C(5)H(5)N)], displays a square-planar coordination geometry around the Ni(II) ion, formed by the tridentate hydrazone and monodentate pyridine ligands, with the N atoms in a trans arrangement about the Ni center.
Project description:In the title compound, [Cu(C(17)H(15)NO(3))(C(3)H(4)N(2))], the Cu(II) atom is four-coordinated by two O atoms and the N atom of the tridentate Schiff base ligand, and one N atom from the imidazole ligand in a distorted square-planar geometry. In the crystal structure, mol-ecules are linked into dimers by inter-molecular N-H?O hydrogen bonds.
Project description:The mol-ecule of the title compound, C(18)H(13)N(3)O(5), displays an E configuration with respect to the C=N double bond. The dihedral angle between the benzene ring and the naphthyl system is 1.1?(2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H?O and O-H?O hydrogen bonds, forming a three-dimensional network.
Project description:The unit cell of the title compound, [Zn(C17H18N3O4)2]·CH4O·C2H6O, contains two complex mol-ecules related by an inversion centre, plus one methanol and one ethanol solvent molecule per complex molecule. In each complex, two deprotonated pyridine aroylhydrazone ligands {3,4,5-trimeth-oxy-N'-[1-(pyridin-2-yl)ethyl-idene]benzohydrazide} coordinate to the ZnII ion through the N atoms of the pyridine group and the ketamine, and, additionally, through the O atom of the enolate group. In the crystal, dimers are formed by ?-? inter-actions between the planar ligand moieties, which are further connected by C?O and C?C inter-actions. The inter-molecular inter-actions were investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing that the most important contributions for the crystal packing are from H?H (44.8%), H?C/C?H (22.2%), H?O/O?H (18.7%) and C?C (3.9%) inter-actions.
Project description:The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·H(2)O, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is almost planar (r.m.s. deviation for all non-H atoms = 0.040 Å). The amido N atom is the hydrogen-bond donor to the water mol-ecule, which is the hydrogen-bond donor to the hydr-oxy groups of two neighboring mol-ecules. One of the hydroxyl groups acts as an intra-molecular and the other as an inter-molecular hydrogen-bond donor.
