Treatment of the Lambda(LLL)Lambda(LLL) and Delta(LLL)Delta(LLL) isomers of K-3[Co{ Co(L-cys-N,S)(3))(2)] (K-3[1], L-cys L-cysteinate) with Ln(NO3)(3) (Ln = La and Yb) in water gave coordination polymers, Lambda(LLL)Lambda(LLL)-Ln[1] and Delta(LLL)Delta(LLL)-Ln[1], respectively, in which [1](3-) binds to Ln(3+) through carboxylate groups in a 1 1 ratio It was found that the dimensional structures of Ln[1] are controlled not only by the diastereoisomerism of [1](3-) (Lambda(LLL)Lambda(LLL) vs Delta(LLL)Delta(LLL)) but also by the ionic size of Ln(3+) (La3+ vs Yb3+)
