摘要

The crystal structures of mixed coordination compounds, Cu(2)Gly(D-Ser)(L-Ser)_2 (I) and Cu(2)Gly_3(L-Ser) (II), which contain the amino acid residues of glycine (Gly) and serine (Ser) in the 1:3 and 3:1 ratio, respectively are studied by electron diffraction. Crystals I and II are triclinic, Z = 1, and space group P1. For I, a = 8.96(2) A, b = 9.66(2) A, c = 5.07(2) A,α = β = 90°, and γ = 92.8(3)°. For II a = 8.37(2) A, b = 9.65(2) A, c = 5.06(2) A, α = β = 90°, and γ = 92.8(3)°. Compounds I and II have layered structures that are based on the CuGly(L-Ser) fragment. Structures I and II differ mainly in their interlayer spacing and configuration of the interlayer space.
