Co-crystal structure of a dinuclear (Zn–Y) and a trinuclear (Zn–Y–Zn) complex derived from a Schiff base ligand

Abstract

The very dynamic field of research for the design and synthesis of heteropolynuclear complexes of d and f-block elements has made it possible to generate original structures with interesting properties in various fields such as magnetism, optics, catalysis and luminescence.The present investigation describes the synthesis and structural study of two complexes. The complex 1 is a Heterotrinuclear complexes synthesis which was used to generate three dimensional complexes formulated as [{Ni(L)}(K){Ni(L)}](SCN). The compound crystallizes in the Monoclinic system Space group P21/c with the following unit cell dimensions a = 11.5891(13) Å b = 17.307(2) Å c = 19.781(2) Å and b= 92.368(10)°, R1= 0.1172. In the compound the ligand H2L is hexadentate. In the unit the coordination environment of the Ni metal can be described as distorted square, the alkaline metal K is octacoordinated.
