Bis{4-chloro-N'-[phen-yl(2-pyrid-yl)methyl-idene]benzohydrazidato-κN',O}cobalt(III) nitrate methanol disolvate.

ABSTRACT: In the title compound, [Co(C(19)H(13)ClN(3)O)(2)]NO(3)·2CH(3)OH, the central Co(III) atom in the cation is surrounded by two tridentate ligands in a distorted octa-hedral fashion by four N and two O atoms. Classical O-H⋯O hydrogen bonds link both methanol solvent mol-ecules with the nitrate anion.

Project description:In the title complex, [Mn(NCS)(2)(C(6)H(7)NO)(2)], the Mn(II) atom shows site symmetry 2.

Bis[N'-(9H-fluoren-9-yl-idene)benzohydrazidato-κN',O]copper(II).

Project description:In the title complex, [Cu(C(20)H(13)N(2)O)(2)], the Cu(II) ion is tetra-coordinated by an N(2)O(2) set of two ligands in a distorted recta-ngular-planar geometry. The dihedral angle between the two coordinated five-membered metalla rings is 37.5 (3)°. The mol-ecular configuration is stabilized by two C-H⋯O and two C-H⋯N intra-molecular hydrogen bonds. The crystal packing is dominated by van der Waals inter-actions. Three atoms of the phenyl ring of the benzohydrazidate moiety are disordered over two sets of sites in a 0.625 (18):0.375 (18) ratio.

Dichloridobis(7-amino-2,4-dimethyl-1,8-naphthyridine-κN,N')cobalt(II) methanol disolvate.

Project description:The title compound, [CoCl(2)(C(10)H(11)N(3))(2)]·2CH(3)OH, crystallizes with an elongated Co coordination polyhedron in a very distorted octa-hedral geometry. Both naphthyridine ligands coordinate to the Co atom via two N atoms in a bidentate chelating mode. The remaining coordination sites are occupied by two Cl atoms. Two uncoordinated solvent methanol mol-ecules are hydrogen bonded to the Cl atoms. Additional N-H⋯O, C-H⋯Cl and N-H⋯Cl hydrogen bonds, and π-π stacking inter-actions [centroid-centroid distance 3.664 (4) Å], give rise to a three-dimensional network structure.

Bis[?-3,5-bis-(2-pyrid-yl)pyrazolato]bis-(hydrogensulfato)-dicopper(II) methanol disolvate.

Project description:The title compound, [Cu(2)(C(13)H(9)N(4))(2)(HSO(4))(2)]·2CH(3)OH, consists of discrete centrosymmetric dinuclear complex mol-ecules and methanol solvent mol-ecules. The Cu(II) atom shows a square-pyramidal coordination geometry and is bonded to four N atoms of the two bis-chelating 3,5-bis-(2-pyrid-yl)pyrazol-ate ions (bpypz(-)) and one O atom of the hydrogensulfate ion. The bpypz(-) ligands in the complex mol-ecule are virtually coplanar [dihedral angle between the mean ligand planes = 0.000(1)°] with the Cu(II) atom deviating in opposite directions from their best plane by 0.2080?(12)?Å. ?-? stacking inter-actions between the pyridyl and pyrazole rings [centroid-centroid distance = 3.391?(3)?Å] and strong O-H?O hydrogen bonds between the hydrogensulfate ligands and the methanol mol-ecules assemble the mol-ecules into a one-dimensional polymeric structure extending along the a axis. The methanol mol-ecule acts both as an accepter and a donor in the hydrogen bonding.

Project description:In the title complex, [V(C(18)H(11)ClN(2)O(2))(CH(3)O)O(CH(3)OH)], the V(V) ion is coordinated by a tridendate 3-chloro-N'-(2-oxidonaphthalen-1-ylmethylidene)benzohydrazidate ligand, one oxido ligand and by O atoms from a methanol and a methoxide ligand, forming a distorted octa-hedral geometry.

In the crystal, pairs of inter-molecular O-H⋯N hydrogen bonds form centrosymmetric dimers.
