Di-aqua-bis-(3-chloro-benzoato-?O)bis-(nicotinamide-?N (1))cobalt(II).

ABSTRACT: 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). ?-? stacking between parallel pyridine rings of adjacent mol-ecules [centroid-centroid distance = 3.7765?(8)?Å] further stabilizes the crystal structure.

Project description:The asymmetric unit of the mononuclear cobalt complex, [Co(C11H13O2)2(C6H6N2O)2(H2O)2]·2H2O, contains one half of the complex mol-ecule, one coordinating and one non-coordinating water mol-ecule, one 4-tert-butyl-benzoate (TBB) ligand and one nicotinamide (NA) ligand; the Co atom lies on an inversion centre.

The four nearest O atoms around the Co atom form a slightly distorted square-planar arrangement, with the distorted octa-hedral coordination completed by the two pyridine N atoms of the NA ligands at distances of 2.1638 (11) Å. The coordinating water mol-ecules are hydrogen bonded to the carboxyl O atoms [O ⋯ O = 2.6230 (17) Å], enclosing an S(6) hydrogen-bonding motif, while inter-molecular O-H⋯O hydrogen bonds link two of the non-coordinating water mol-ecules to the coordinating water mol-ecules and NA anions. The dihedral angle between the planar carboxyl-ate group and the adjacent benzene ring is 29.09 (10)°, while the benzene and pyridine rings are oriented at a dihedral angle of 88.53 (4)°. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules, enclosing R 2 (2)(8), R 2 (2)(10) and R 4 (4)(12) ring motifs, forming layers parallel to (001). The C and H atoms of the tert-butyl group of the TBB ligand are disordered over two sets of sites with an occupancy ratio of 0.631 (5):0.369 (5).

Crystal structure of di-aqua-bis-(N,N-di-ethyl-nicotinamide-?N (1))bis-(2,4,6-tri-methyl-benzoato-?O (1))cobalt(II).

Project description:The centrosymmetric mol-ecule in the monomeric title cobalt complex, [Co(C10H11O2)2(C10H14N2O)2(H2O)2], contains two water mol-ecules, two 2,4,6-tri-methyl-benzoate (TMB) ligands and two di-ethyl-nicotinamide (DENA) ligands. All ligands coordinate to the Co(II) atom in a monodentate fashion. The four O atoms around the Co(II) atom form a slightly distorted square-planar arrangement, with the distorted octa-hedral coordination sphere completed by two pyridine N atoms of the DENA ligands. The dihedral angle between the planar carboxyl-ate group and the adjacent benzene ring is 84.2?(4)°, while the benzene and pyridine rings are oriented at a dihedral angle of 38.87?(10)°. The water mol-ecules exhibit both intra-molecular (to the non-coordinating carboxyl-ate O atom) and inter-molecular (to the amide carbonyl O atom) O-H?O hydrogen bonds. The latter lead to the formation of layers parallel to (100), enclosing R 4 (4)(32) ring motifs. These layers are further linked via weak C-H?O hydrogen bonds, resulting in a three-dimensional network. One of the two ethyl groups of the DENA ligand is disordered over two sets of sites with an occupancy ratio of 0.490?(13):0.510?(13).

Poly[?-aqua-bis-(?5-2,4-di-chloro-benzoato)dipotassium].

Project description:In the title compound, [K2(C7H3Cl2O2)2(H2O)] n , the potassium salt of 2,4-di-chloro-benzoic acid, the repeating unit in the polymeric structure consists of two identical irregular KO6Cl units related by twofold rotational symmetry, linked by a bridging water mol-ecule lying on the twofold axis. The coordination polyhedron about the K(+) ion comprises a carboxyl-ate O atom and a Cl-atom donor from a bidentate chelate ligand inter-action, four O-atom donors from a doubly bridging bidentate carboxyl-ate O,O'-chelate inter-action and the water mol-ecule. A two-dimensional polymeric structure lying parallel to (100) is generated through a series of conjoined cyclic bridges between K(+) ions and is stabilized by water-carboxyl-ate O-H?O hydrogen-bonding inter-actions.
