ABSTRACT: In the title compound, [Cu(C(13)H(13)Cl(2)NO(3))(C(3)H(7)NO)], the Cu(II) atom is coordinated in a slightly distorted square-planar geometry by two O atoms and one N atom from the tridentate chiral ligand 2-[(3,5-dichloro-2-oxidobenzyl-idene)amino]-3-methyl-penta-noate and by one O atom from dimethyl-formamide. In the crystal structure, the Cu atom forms contacts with Cl and O atoms of two units (Cu⋯Cl and Cu⋯O = 3.401 and 2.947 Å, respectively), thereby forming an approximately octa-hedral arrangement. A three-dimensional network is constructed through Cl⋯Cu, O⋯Cu, Cl⋯Cl contacts and C-H⋯O hydrogen bonds.
Project description:In the title compound, [Cu(C(13)H(14)BrNO(3))(C(12)H(8)N(2))]·2H(2)O, the Cu(II) atom is penta-coordinated in a square-pyramidal geometry. The crystal packing is stabilized by O-H⋯O hydrogen bonds.
Project description:In the title complex, [Cu(C(16)H(11)Cl(2)NO(4))(C(3)H(7)NO)] , the Cu(II) atom is coordinated by two O atoms and one N atom from the tridentate ligand L(2-) {LH(2) = (2S)-[2-(3,5-dichloro-2-hydroxy-benzyl-idene)-imino]-3-(4-hydroxy-phenyl)propionic acid} and one O atom from a dimethyl-formamide mol-ecule, resulting in a slightly distorted square-planar geometry. The structure forms a one-dimensional chain through weak coordination bonds [Cu⋯O 3.080 (1), Cu⋯Cl 3.269 (1) Å] and a three-dimensional network through O-H⋯O and C-H⋯O hydrogen bonds.
Project description:In the title compound, [Cu(C(8)H(5)Cl(2)N(3)OS)(C(3)H(7)NO)]·C(3)H(7)NO, the Cu(II) atom is coordinated in a slightly distorted square-planar geometry by an O, an S and an N atom from the tridentate ligand 3,5-dichloro-salicylaldehyde thio-semi-carb-azonate ligand and one O atom from dimethyl-formamide. At the same time, the Cu atom is in contact with S and Cl atoms from another two complexes [Cu⋯S and Cu⋯Cl = 2.9791 (2) and 3.3800 (3) Å, respectively], thereby forming a [4 + 2] coordination geometry. The crystal structure exhibits N-H⋯O and N-H⋯N hydrogen bonds.
Project description:In the crystal structure of the title compound, [Sn(CH(3))(2)(C(9)H(8)N(2)O(3))(C(10)H(8)N(2))], the Sn atom exhibits a penta-gonal bipyramidal coordination geometry defined by two C, three N and two O atoms. The bond distances for Sn-C, Sn-N and Sn-O are in the ranges 2.097 (3)-2.098 (3), 2.298 (2)-2.623 (2) and 2.157 (2)-2.266 (2) Å, respectively. The mol-ecular structure of the monomeric compound is stabilized by three intra-molecular C-H⋯O hydrogen bonds, all involving bipyridine C-H groups.
Project description:In the title complex, [Mn(C(7)H(5)O(3))(C(27)H(27)N(7))(C(3)H(7)NO)]ClO(4)·C(3)H(7)NO, the Mn(II) ion is coordinated in a slightly distorted monocapped trigonal-prismatic geometry. The tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand coordinates in a tetra-dentate mode and the coordination is completed by a bis-chelating salicylate ligand and a dimethyl-formamide ligand. The hy-droxy group and the ortho H atoms of the salicylate ligand were refined as disordered over two sites with occupancies of 0.581 (8) and 0.419 (8). Both disorder components of the hy-droxy group form intra-molecular O-H⋯O hydrogen bonds.
Project description:The tridentate Schiff base ligand of the title complex, [V(C(15)H(12)N(2)O(4))O(C(12)H(8)N(2))]·C(3)H(7)NO, was derived from the condensation of 2-hy-droxy-1-naphthaldehyde and l-asparagine. The central V(IV) atom is six-coordinated by one oxide O atom, two N atoms from 1,10-phenanthroline and one N atom and two O atoms from the Schiff base ligand in a distorted octa-hedral geometry. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds connect mol-ecules into centrosymmetric dimers. The C atoms of the dimethyl-formamide solvent mol-ecule are disordered over two sites with site-occupancy factors of 0.732 (13) and 0.268 (13).
Project description:In the mononuclear title compound, [Co(III)(C(15)H(12)N(2)O(3))(C(5)H(5)N)(3)]ClO(4), the Co(III) ion is coordinated by three pyridine mol-ecules and one N'-(3-meth-oxy-2-oxidobenzyl-idene)benzohydrazidate Schiff base ligand in an O,N,O'-tridentate manner. The Co(III) ion adopts a distorted CoN(4)O(2) octa-hedral coordination environment.
Project description:In the title compound, [Ni(C(7)H(3)Cl(2)O(2))(2)(C(3)H(7)NO)(H(2)O)], the Ni(II) ion is coordinated by four O atoms from two bidentate 2,4-dichloro-6-formyl-phenolate ligands, one O atom from a water ligand and one O atom from a dimethyl-formamide ligand in a slightly distorted octa-hedral environment. In the crystal structure, centrosymmetric dimers are formed though O-H⋯O and O-H⋯Cl hydrogen bonds; π-π stacking inter-actions, with a centroid-centroid distance of 3.796 (2) Å, are also found.
Project description:In the title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)(H(2)O)], the Cu(II) atom is coordinated in a slightly distorted square-pyramidal geometry by two N atoms belonging to the two 3,5-dimethyl-1H-pyrazole ligands, two O atoms of the oxalate anion providing an O,O'-chelating coordination mode, and an O atom of the water mol-ecule occupying the apical position. The crystal packing shows a well defined layer structure. Intra-layer connections are realised through a system of hydrogen bonds while the nature of the inter-layer inter-actions is completely hydro-phobic, including no hydrogen-bonding inter-actions.
Project description:In the title compound, [Cu(C(2)H(3)O(2))(2)(C(5)H(8)N(2))(2)], the Cu(II) atom has a distorted tetra-gonal-bipyramidal geometry, with the equatorial plane formed by two N atoms belonging to two 3,5-dimethyl-1H-pyrazole ligands and two O atoms from two acetate anions. The second O atoms of the acetate groups provide elongated Cu-O axial contacts, so that the acetates appear to be coordinated in a pseudo-chelate fashion. The pyrazole ligands are situated in cis positions with respect to each other. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming a one-dimensional chain.
