摘要：

The compounds of formula [Bu4N](2)[Mn-2{Cu(opba)} (3)]. 4DMF . 5H(2)O (BMn) and [Bu4N](2)[Co-2{Cu(opba)}(3)]. DMF . H2O (BCo) have been synthesized (opba = ortho-phenylenebis(oxamato)). BMn shows a spontaneous magnetization below a critical temperature T-c equal to 22 K; for BCo, T-c = 40 K, the strongest for this type of system. While BMn is a soft magnet, BCo exhibits a coercive field of 4 kOe. (C) 2001 Elsevier Science B.V. All rights reserved.
