摘要

The 3D heterometallic polymeric complex 1 {[Nd2Cu2(L)(2)(OXA)(4)center dot 2(2H(2)O)]center dot 2(3H(2)O)}(n) (HL = 2, 2'-bipyridine-3-carboxyic acid, OXA = oxalate) was obtained from hydrothermal reaction of Nd2O3, Cu(ClO4)(2), HL and oxalic acid in the presence of ethanol and water. X-ray single crystal diffraction investigation of the polymeric complexes {[Nd2Cu2(L)(2)(OXA)(4)center dot 2(2H(2)O)]center dot 2(3H(2)O)}(n) exhibits an interesting and novel topological structure.
