| Abstract: | Two novel mixed valence copper coordination polymers, Cu(2-pac)2(CuN3)(H2O)] n (1) and Cu(2-pac)2(CuSCN)2] n (2), have been prepared through hydrothermal synthesis and analyzed for structure determination, which exhibit two- and three-dimensional structures respectively. In complex (1), zigzag chains of CuN3] n running parallel to thec direction are interconnected by Cu(2pac)2 to form a two-dimensional layer structure. In complex (2), the arrangement of μ-1,1,3 bridging thiocyanate ligand leads to the formation of ten-membered Cu—SCN— Cu—S—Cu—NCS rings, and each Cu atom is further linked by Cu(2-pac)2 to afford a three-dimensional configuration. |
