The title compound Cd（Eim）3Cl2 （Eim = N-ethylimidazole） I has been synthesized and structurally characterized by single-crystal X-ray diffraction. The compound crystallizes in the monoclinic system, space group P2 1 with a = 8.0460（16）, b = 29.186（6）, c = 8.8960（18）A,β= 100.06（3）°, C15H24CdCl2N6, Mr = 471.71, V = 2056.9（7）A^3 Z = 4, Dc = 1.523 g/cm^3,/1 = 1.330 mm^-1, F（000） = 952, the final R = 0.0455 and wR = 0.0723. The title compound crystallizes with two molecules in the asymmetric unit. Each Cd^II ion is coordinated by three Eim ligands and two Cl anions in a trigonal bipyramidal geometry in two molecules. The weak intermolecular C-H……Cl hydrogen bonds link the molecules into two independent hydrogen-bonded chains running along the c axis. According to the cyclic voltammogram measurement in H2O, the electrode reaction should be a quasi-reversible process.
The title compound I （C22H24MnN10S2, Mr = 547.57） has been synthesized and structurally characterized by single-crystal X-ray diffraction. The compound crystallizes in the monoclinic system, space group P2 1/c with a = 8.6010（17）, b = 9.0180（18）, c = 17.773（4）A, β = 101.79（3）°, V = 1349.5（5）A^3, Z = 2, Dc = 1.348 g/cm^3,/1 = 0.674 mm^-1, F（000） = 566, the final R = 0.0488 and wR = 0.1289. In the structure, each Mn atom is coordinated by four Vim （Vim = 1-vinylimidazole） ligands and a pair of monodentate isothioeyanic groups, affording a compressed oetahedral MnN6 core.
A complex [Mn(NCS)2(Eim)4](where Eim=1-ethylimidazole)has been synthesized and structurally cha-racterized by X-ray diffraction single-crystal structure analysis.The compound crystallizes in the Orthorhombic space group Pbca with the cell parameters:a=1.618 9(3)nm,b=1.787 4(4)nm,c=1.999 4(4)nm,and V=5.786(2)nm3,Z=8.In the structure,each Mn atom is coordinated by four Eim ligands and a pair of monodentate isothiocyanic groups,affording a compressed octahedral MnN6 core.The NCS-anions are trans and four N atoms from the Eim ligands define the equatorial plane.The C-H…π supramolecular interactions between C-H and imidazole rings of Eim link the molecules into independent chains running along the c-axis.The thermal gravity(TG)data indicates that thermal decomposition of the title complex takes place in two steps,the residue is Fe.CCDC:646113.
