Di-aqua-bis-(nicotinamide-?N (1))bis-(thiocyanato-?S)cobalt(II).

ABSTRACT: In the title compound, [Co(NCS)2(C6H6N2O)2(H2O)2], the Co(II) cation is located on an inversion centre and is coordinated by two thio-cyanate anions, two nicotinamide mol-ecules and two water mol-ecules in a distorted N2O2S2 octa-hedral geometry. The amide group is twisted by 31.30?(16)° with respect to the pyridine ring. In the crystal, mol-ecules are linked by O-H?O, O-H?S and N-H?S hydrogen bonds into a three-dimensional supra-molecular network. Weak ?-? stacking is observed between parallel pyridine rings of adjacent mol-ecules, the centroid-centroid distance being 3.8270?(19)?Å.

Crystal structure of di-aqua-bis-(4-tert-butyl-benzoato-κO)bis-(nicotinamide-κN (1))cobalt(II) dihydrate.

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. All ligands coordinating to the Co atom are monodentate. 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-κN (1))bis-(2,4,6-tri-methyl-benzoato-κO (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).

Di-aqua-bis-(nicotinamide-?N (1))bis-(thio-cyanato-?N)nickel(II).

Project description:In the title complex, [Ni(NCS)2(C6H6N2O)2(H2O)2], the Ni(II) ion is located on an inversion center and is coordinated in a distorted octa-hedral environment by two N atoms from two nicotinamide ligands and two water mol-ecules in the equatorial plane, and two N atoms from two thio-cyanate anions in the axial positions, all acting as monodentate ligands. In the crystal, weak N-H?S hydrogen bonds between the amino groups and the thio-cyanate anions form an R 4 (2)(8) motif. The complex mol-ecules are linked by O-H?O, O-H?S, and N-H?S hydrogen bonds into a three-dimensional supra-molecular structure. Weak ?-? inter-actions between the pyridine rings is also found [centroid-centroid distance = 3.8578?(14)?Å].

Project description:In the title compound, [Co(2)(C(2)H(3)O(2))(4)(C(7)H(6)N(2))(4)(H(2)O)], the half-mol-ecule in the asymmetric unit is completed by a crystallographic twofold rotation axis to give the full mol-ecule.

The compound features intra-molecular O-H⋯O hydrogen bonds between the non-bridging acetate groups and the bridging water mol-ecule, and inter-molecular N-H⋯O hydrogen bonds between the acetates and amine H atoms of the benzimidazoles which determine the mol-ecular packing in the crystal structure.

Project description:The title compound, [Cu(C7H4ClO2)2(C10H14N2O)2(H2O)], has twofold symmetry with the Cu(II) cation and the O atom of the coordinating water mol-ecule located on the axis.

The benzene and pyridine rings are oriented at a dihedral angle of 82.51 (6)°. In the anionic ligand, the carboxyl-ate group is twisted away from the attached benzene ring by 12.85 (11)°. In the crystal, O-H⋯O hydrogen bonds between the coordinating water mol-ecule and the carboxyl group link the complex mol-ecules into supra-molecular chains running along the c-axis direction.
