本文报道了氰基桥联钆钨酸盐组装体GdIII（DMF）6[WV（CN）8]（DMF =N，N-二甲基甲酰胺）的晶体结构和磁性。X射线单晶分析表明，该化合物属于单斜晶系，空间群为P2（1）/c，晶胞常数a= 16.40（2）A，B= 11.08（1）A，c= 21.18（2）A，β = 91.09（8）度，Z= 4。晶体由一维线性链组成，其中[GdIII（DMF）6]3+和[WV（CN）8]3-离子以交替方式连接。磁性数据表明，该化合物为顺磁体，Gd Ⅲ（S= 7/2）和WV（S= 1/2）之间的反铁磁耦合为-0.58cm ~（-1）。
In this paper, we report the crystal structure and magnetic properties of the cyano-bridged gadolinium-tungstate bimetallic assembly, GdIII(DMF)6[WV(CN)8](DMF =N,N-dimethylformamide). X-Ray single crystal analysis shows that this compound crystallizes in the monoclinic system of space group P2(1)/c with cell constants a= 16.40(2)A, b= 11.08(1)A, c= 21.18(2)A, beta= 91.09(8) degrees, and Z= 4. The crystal consists of one-dimensional linear chains, in which [GdIII(DMF)6]3+ and [WV(CN)8]3- ions are linked in an alternating fashion. The magnetic data show that this compound is a paramagnet with an antiferromagnetic coupling of -0.58 cm-1 between GdIII(S= 7/2) and WV(S= 1/2).
