Diaqua-bis(4-bromo-2-formyl-phenolato-?O,O')cobalt(II).

ABSTRACT: In the title complex, [Co(C(7)H(4)BrO(2))(2)(H(2)O)(2)], the Co(II) ion, which lies on a crystallographic inversion center, is coordin-ated by four O atoms from two bidentate 4-bromo-2-formyl-phenolate ligands and two O atoms from two water ligands in a slightly distorted octa-hedral environment. In the crystal structure, one-dimensional chains are formed through inter-molecular O-H?O hydrogen bonds, which are further linked into a two-dimensional network through Br?Br inter-actions [Br?Br = 3.772?(4)?Å].

Project description:The crystal of the title compound, [Zn(C(7)H(3)Cl(2)O(2))(2)(H(2)O)(2)](2)·[Zn(2)(C(7)H(3)Cl(2)O(2))(4)(H(2)O)(2)], consists of monomeric and dimeric Zn(II) complexes. Both complexes afford a six-coordinated coordination environment about the Zn atoms with cis-configuration ligands. The deprotonated hydr-oxy groups of the 3,5-dichloro-salicylaldehyde ligands bridge two metal cations, forming a centrosymmetric dimeric complex. Inter-molecular O-H?O hydrogen bonding occurs between the coordinated water mol-ecules and deprotonated hydr-oxy groups in the crystal structure.

Diaqua-bis-(4-formyl-benzoato-?O(1))bis-(nicotinamide-?N(1))cobalt(II).

Project description:In the title complex, [Co(C(8)H(5)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Co(II) cation is located on an inversion center and is coordinated by two 4-formyl-benzoate (FB) anions, two nicotinamide (NA) ligands and two water mol-ecules. The four O atoms in the equatorial plane around the Co(II) cation form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 23.91?(9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 88.84?(4)°. The coordinating water mol-ecule links with the carboxyl-ate group via an intra-molecular O-H?O hydrogen bond. In the crystal, N-H?O, O-H?O and weak C-H?O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network. ?-? stacking between the parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.8505?(8)?Å] may further stabilize the structure. A weak C-H?? inter-action also occurs in the crystal.

Diaqua-bis(N,N-diethyl-nicotinamide-κN)bis-(4-formyl-benzoato-κO)cobalt(II).

Project description:In the crystal structure of the title Co(II) complex, [Co(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the metal centre is located on an inversion center and is coordinated by two 4-formyl-benzoate (FOB), two diethyl-nicotinamide (DENA) ligands and two water mol-ecules in a slightly distorted CoO(4)N(2) octa-hedral geometry. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into infinite chains. π-π contacts between the parallel pyridine rings of neighboring DENA ligands [centroid-centroid distance = 3.652 (3) Å] further stabilize the crystal structure.

Diaqua-bis-(2-bromo-benzoato-κO)bis-(N,N-diethyl-nicotinamide-κN)cobalt(II).

Project description:In the mononuclear title compound, [Co(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Co(II) ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 2-bromo-benzoate anion, one diethyl-nicotinamide (DENA) ligand and one coordinated water mol-ecule; all ligands are monodentate. The four O atoms in the equatorial plane around Co(II) form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the DENA ligands in axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 84.7 (1)°; the pyridine and benzene rings are oriented at a dihedral angle of 43.64 (6)°. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Bis{?-2-[(pyridin-2-yl)imino-meth-yl]phenolato}bis-[(2-formyl-phenolato)copper(II)].

Project description:The asymmetric unit of the title compound, [Cu(2)(C(12)H(9)N(2)O)(2)(C(7)H(5)O(2))(2)], contains two independent (2-formyl-phen-olato){2-[(pyridin-2-yl)imino-meth-yl]phenolato}copper(II) mol-ecules that form pseudocentrosymmetric dimers via inter-actions between the Cu and pyridyl N atoms of independent monomers. The square-planar geometry of the Cu atoms in the monomer thus becomes square-based pyramidal in the dimer. The crystal studied was an inversion twin, with unequal populations of 0.353?(17) and 0.647?(17).

Diaqua-bis-(dimethyl sulfoxide-?O)bis(saccharinato-?N)cobalt(II).

Project description:The title complex, [Co(C(7)H(4)NO(3)S)(2)(C(2)H(6)OS)(2)(H(2)O)(2)], contains a Co(2+) cation in an octa-hedral coordination environment. The metal atom is surrounded by two different neutral ligands, namely dimethyl-sulfoxide (DMSO) and water, each coordinating through the O atom. The anionic saccharinate (sac; 1,1,3-trioxo-2,3-dihydro-1?(6),2-benzothia-zol-2-ide) ligand coordinates through the N atom. Each of the three similar ligand pairs is in a trans configuration with respect to each other. The Co atom lies on a crystallographic center of symmetry and the octa-hedral geometry is not significantly distorted. A short O-H?O hydrogen bond is present between a water H atom and the ketone O atom; two longer hydrogen bonds (intra- and inter-molecular) are also present between a water H and a sulfonic O atom, forming a supramolecular assembly through head-to-tail aggregation between adjacent complexes.
