摘要：

A novel pyroelectric ferrimagnet, [{Mn-II(pyrazine)(H2O)(2)}{Mn-II(H2O)(2)}{Nb-IV(CN)(8)}]center dot 4H(2)O, is synthesized. The crystal consists of an Nb-IV-CN-Mn-II linked three-dimensional network, which has an electric polarization along the b axis. This compound exhibits ferrimagnetism with a Curie temperature of 48K due to the antiparallel ordering of magnetic spins on Nb-IV (S = 1/2) and those on Mull (S = 5/2).
