Synthesis and physico-chemical studies of a novel layered structure with a heptanuclear Cd complex: (C9N4H28)Cd-7(H2O)(2)Cl-18 center dot nH(2)O(n=5.89)

摘要

The inorganic-organic hybrid compound (C9N4H28)Cd-7(H2O)(2)Cl-18 center dot nH(2)O(n = 5.89) features an unusual cadmium chloride structure. The title complex adopts a layered structure consisting of double-chains and tetramers of [Cd phi(6)] (phi = Cl, O) octahedra. Crystallization water molecules and [C9H28N4](4+) tetracations are located in interstices of the successive corrugated layers. This compound has also been investigated by FT-IR and solid-state C-13, N-15 CP-MAS and 2D C-13-H NMR spectroscopies. (C) 2014 Elsevier B.V. All rights reserved.
