A novel metal-organic coordination polymer with unprecedented floor-like structural configuration consisting of two kinds of independent building blocks of triple- and double-stranded braids

This paper presents a novel and distinctive metal-organic compound, {[Cd4(bet)4Cl6(H2O)4][Cd2Cl6]}n (bet=(CH3)3NCH2CO2, namely betaine) 1, assembled from two independent building blocks of triple- and double-stranded braids, and characterized by an unprecedented floor-like structural configuration. Furthermore, IR, element analysis, and TG-DTA were employed to characterize it. Compound 1 belongs to triclinic system, space group P-1, a = 6.704(2) Å, b = 9.338(3) Å, c = 20.056(7) Å, α = 101.409(5)°, β = 96.650(5)°, γ = 93.148(5)°, V = 1218.5(7) Å3, Z = 1, R1 = 0.0340, ωR2 = 0.1017.
