摘要

Crystals of [Co(C_2H_8N_2)_2(C_3H_6NO_2)]PbCl_4·H_2O [a = 7.627(1) A, b = 11.238(1) A, c = 11.444(1) A, α = 99.125(1)°, β = 103.80(1)°, γ = 94.739(1)°, V = 933.09(1) A~3, Z = 2, and space group P1-bar] contain the octahedral PbCl_6 groups that share edges to form infinite [Cl_2Pb(μ-Cl)_2]_n~(2n-) chains, in which the terminal Cl atoms occupy the cis positions. The Pb-Cl bond lengths are 2.763(1)-3.180(3) A. In the discrete cationic complexes, the Co atom is coordinated by two ethylenediamine molecules and the 3-aminopropionate anion. In the enantiomeric complex with the Δ absolute configuration, the ethylenediamine rings have the λ and δ configurations and the aminopropionate ring has the λ configuration.
