Synthesis and physico-chemical studies of a novel layered structure with a heptanuclear Cd complex: (C9N4H28)Cd7(H2O)2Cl18·nH2O(n = 5.89).

The inorganic–organic hybrid compound (C 9 N 4 H 28 )Cd 7 (H 2 O) 2 Cl 18 · n H 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 ϕ 6 ] ( ϕ = Cl, O) octahedra. Crystallization water molecules and [C 9 H 28 N 4 ] 4+ tetracations are located in interstices of the successive corrugated layers. This compound has also been investigated by FT-IR and solid-state 13 C, 15 N CP-MAS and 2D 13 C-H NMR spectroscopies. [ABSTRACT FROM AUTHOR]
