چکیده
The mol-ecule of the title Cu(II) complex, [Cu(C7H4ClO2)2(C6H6N2O)2], contains two 3-chloro-benzoate (CB) and two nicotinamide (NA) ligands; the CB act as bidentate ligands, while the NA are monodentate ligands. The resulting CuN2O4 coordination polyhedron is a considerably distorted octahedron. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 17.92 (12) and 24.69 (16)°, while the two benzene rings and the two pyridine rings are oriented at dihedral angles of 52.20 (8) and 1.56 (6)°. In the crystal, N-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. The π-π contact between the benzene rings [centroid-centroid distance = 3.982 (2) Å] may further stabilize the crystal structure.

In the title compound, [Cu(C(7)H(4)ClO(2))(2)(C(5)H(6)N(2))(2)], each Cu(II) ion, located on an inversion center, has a slightly distorted square-planar coordination geometry formed by two 1-vinyl-imidazole mol-ecules [Cu-N = 1.954 (6) Å] and two 2-chloro-benzoate anions [Cu-O = 1.958 (6) Å]. Weak inter-molecular C-H⋯O hydrogen bonds contribute to the crystal packing stability.

In the title centrosymmetric binuclear Cu(II) complex, [Cu2(C7H4ClO2)4(C10H14N2O)2], the two Cu(II) cations [Cu⋯Cu = 2.6314 (4) Å] are bridged by four 3-chloro-benzoate (CB) anions. The four carboxyl-ate O atoms around each Cu(II) cation form a distorted square-planar arrangement, the distorted square-pyramidal coordination geometry being completed by the pyridine N atom of the N,N-di-ethyl-nic...

The title compound, [Zn(C(7)H(4)FO(2))(2)(C(6)H(6)N(2)O)(2)]·H(2)O, is a monomeric complex. It contains two 4-fluoro-benzoate and two nicotinamide ligands and one uncoordinated water mol-ecule. The 4-fluoro-benzoates act as bidentate chelating ligands, while the nicotinamides are monodentate. The six-coordinate geometry around the Zn(II) atom may be described as highly distorted octa-hedral, wi...

In the title compound, [Cu(2)(C(7)H(4)ClO(2))(4)(C(12)H(8)N(2))(2)]·2H(2)O, the two crystallographically independent dinuclear complex mol-ecules, A and B, have different Cu⋯Cu separations, viz. 3.286 (1) Å in A and 3.451 (1) Å in B. Both independent mol-ecules reside on inversion centres, so the asymmetric unit contains a half-mol-ecule each of A and B and two water mol-ecules. Each Cu atom ha...
