The structures of [Cu(S_2CN(CH_2)_4)_2] (1) and [Zn_2(S_2CN-(CH_2)_4)_4] (2) have been determined by X-ray crystallography analysis. They are all isomorphous and triclinic, space group of P1, with Z=1. The lattice parameters of compound 1 is: a=0.63483(2) nm, b=0.74972(3) nm, c=0.78390(1) nm, α=75.912(2)°, β=78.634(2)° and γ=86.845(2)°; compound 2: a=0.78707(6) nm, b=0.79823(6) nm, c=1.23246(9) nm, α=74.813(2)°, β=73.048(2)° and γ=88.036(2)°. The copper atom is located on a crystallographic inversion center and zinc atom lies across centers of symmetry. The Cu(II) ion has a square-planar geometry while Zn(II) has a distorted tetrahedral geometry. The thermal gravity (TG) data indicate that no structural transitions in the two compounds were abserved and the decomposition products can adsorb gas. Also they all have a high thermal stability.
