چکیده
In the dinuclear centrosymmetric title compound, [Cd2(C8H7O2)4(C6H6N2O)2(H2O)2], the Cd(II) ion is chelated by two carboxyl-ate groups from 4-methyl-benzoate anions, and is further coordinated by one nicotinamide and one water mol-ecule; a carboxyl-ate O atom from an adjacent 4-methyl-benzoate anion bridges to the Cd(II) ion, completing the irregular coordination sphere of the seven ligand atoms. In the crystal, inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. The methyl-benzene moiety of one bridging 4-methyl-benzoate anion is disordered over two orientations of equal occupancy.

The title samarium coordination polymer, [Sm(3)(C(8)H(7)O(2))(9)](n), was obtained by the hydro-thermal reaction of Sm(NO(3))(3) with 4-methyl-benzoic acid in alkaline aqueous solution. In the asymmetric unit, there are three crystallographically independent Sm(III) ions, two of which are eight-coordinate in a distorted square-anti-prismatic environment, while the third is nine-coordinate in a ...

In the title centrosymmetric binuclear complex, [Cd(2)(NO(2))(4)(C(11)H(9)N(5))(2)], the unique Cd(II) ion is in a distorted dodeca-hedral CdN(3)O(5) coordination environment. The two inversion-related Cd(II) ions are separated by 3.9920 (6) Å and are bridged by two O atoms from two nitrite ligands. There are two types of π-π stacking inter-actions involving symmetry-related pyrazole rings, wit...
