Synthesis, crystal structure, and characterizations of a (6,3)-connected coordination polymer based on cadmium(II) and nickel(II)

Abstract

A novel heteronuclear coordination polymer Cd(1,3-μ-SCN)6Ni2(C2H8N2)2(H2O)2 (I) has been prepared and characterized by elemental analysis, EDS analysis, PXRD and IR spectrum and single-crystal X-ray diffraction. The single-crystal X-ray diffraction analysis revealed that compound I crystallizes in a monoclinic system of space group C2/m with a = 19.427(8), b = 9.622(3), c = 7.261(3) A, β = 105.383(10)°. The compound exhibits a (6,3)-connected two-dimensional layer which is built up from the strict alternation of 6-connected {CdS6} octahedra and 3-connected {NiON5} octahedra.
