Chain and rhomboidal “box”-like polymeric metal complexes of N′,N′-1,2-ethylenebis(pyrin-2thione)
摘要:
The preparations are reported of a range of complexes of Fe-II, Co-II, Ni-II, Cu-I, Ag-I; Zn and Cd with N,N'-1,2-ethylenebis(pyridin-2-thione) (EBPYT) together with relevant spectroscopic data. The compounds Co(EBPYT)Br-2 (1) and [Ni(EBPYT)(3)](ClO4)(2) . 2MeOH . MeNO2 (2) have been studied by X-ray crystallography. Compound 1 has a chain structure in which tetrahedrally coordinated cobalt centres are linked by bridging EBPYT ligands. In compound 2 octahedrally coordinated "NIS6" centres are connected by EBPYT bridges so as to form a polymeric three-dimensional array of rhomboidal "boxes". (C) 1998 Elsevier Science Ltd.
