Abstract
Abstract
A one-dimensional copper-oxalate framework is obtained. The Jahn-Teller distorted Cu(II) is octahedrally coordinated by four O from two bisbidentate oxalates and two N from one bidentate N, N, N’ N’-tetramethyldiamine and forms a one-dimensional zigzag chain. There are hydrogen bonds between H2O and oxalate and between H2O. In one of H2O, the geometry of two O–H and two O…H–O bonds is same as tetrahedron of H2O in ice. Ferromagnetic interaction is observed. No long-range ordering is observed above 2 K
