Tetra-aqua-bis-[4-(pyrazin-2-ylsulfanylmethyl-?N)benzoato]cobalt(II).

ABSTRACT: In the title compound, [Co(C(12)H(9)N(2)O(2)S)(2)(H(2)O)(4)], the Co(II) ion, lying on an inversion center, has an octa-hedral coordination involving two N atoms of two 4-(pyrazin-2-ylsulf-anylmeth-yl)benzoate ligands and four water mol-ecules. In the crystal, O-H?O hydrogen bonds between the coordinated water mol-ecules and uncoordinated carboxyl-ate O atoms, and weak ?-? inter-actions [centroid-centroid distance = 4.105?(2)?Å] between the benzene and pyrazine rings lead to a three-dimensional supra-molecular network.

Tetra-aqua-bis-[4-(pyrazin-2-ylsulfanylmeth-yl)benzoato]manganese(II) dihydrate.

Project description:The title compound, [Mn(C(12)H(9)N(2)O(2)S)(2)(H(2)O)(4)]·2H(2)O, has been synthesized with a flexible asymmetrical bridging ligand, 4-(pyrazin-2-ylsulfanylmeth-yl)benzoic acid (Hpztmb). The Mn(II) ion exhibits a centrosymmetric octa-hedral geometry involving two carboxyl-ate O atoms of two different pztmb ligands and four O atoms of four coordinated water mol-ecules. The packing shows a three-dimensional supra-molecular network via O-H?O and O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.884?(8) and 4.034?(8)?Å] between the benzene ring of one pztmb anion and the pyrazine ring of an adjacent anion.

Di-aqua-bis-(3-chloro-benzoato-κO)bis-(nicotinamide-κN (1))cobalt(II).

Project description:In the title complex, [Co(C7H4ClO2)2(C6H6N2O)2(H2O)2], the Co(II) atom is located on an inversion center and is coordinated by two 3-chloro-benzoate (CB) anions, two nicotinamide (NA) ligands and two water mol-ecules. The four O atoms in the equatorial plane 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 9.14 (9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 82.18 (8)°. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional network lying parallel to (101). π-π stacking between parallel pyridine rings of adjacent mol-ecules [centroid-centroid distance = 3.7765 (8) Å] further stabilizes the crystal structure.

Project description:In the title compound, [Co(C(12)H(8)NO(2))(2)(H(2)O)(4)], the Co atom lies on a twofold rotation axis and has an N(2)O(4) octa-hedral coordination environment formed by four O atoms of water mol-ecules in the equatorial plane and two apical N atoms of pyridine groups. An intricate three-dimensional supra-molecular network is formed by multiple O-H?O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate groups.

Tetra-aqua-bis(isonicotinamide-κN)cobalt(II) bis-(4-formyl-benzoate) dihydrate.

Project description:The asymmetric unit of the crystal structure of the title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(8)H(5)O(3))(2)·2H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 4-formyl-benzoate (FB) counter-anion and an uncoordinated water mol-ecule. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar arrangement with an average Co-O bond length of 2.086 Å; the slightly distorted octa-hedral coordination is completed by the two N atoms of the isonicotinamide (INA) ligands at a slightly longer distance [2.1603 (14) Å] in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 5.93 (13)°, while the pyridine and benzene rings are oriented at a dihedral angle of 3.09 (6)°. In the crystal structure, 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 benzene and pyridine rings [centroid-centroid distance = 3.758 (1) Å] may further stabilize the crystal structure.

Between adjacent chains, π-π inter-actions occur between the pyridine rings [centroid-centroid distance = 3.898 (2) Å], giving an overall two-dimensional architecture.

Bis(2-amino-pyridine-κN)bis-(benzoato-κO)cobalt(II).

Project description:In the title compound, [Co(C(7)H(5)O(2))(2)(C(5)H(6)N(2))(2)], the Co(II) atom is hexa-coordinated by four O atoms from two benzoate anions, and two N atoms from two 2-amino-pyridine mol-ecules, resulting in a distorted octa-hedral geometry. Both benzoate anions act as bidentate ligands and both 2-amino-pyridine mol-ecules are coordinated to the metal through their pyridyl N atoms. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds, C-H⋯π, and π-π stacking inter-actions involving benzoate anions and 2-amino-pyridine mol-ecules.
