摘      要：Three new cyanido-bridged heterometallic ReIVNin and ReIVCu one-dimensional systems were synthesized and extensively characterized both structurally and magnetically. Single-crystal X-ray diffraction analysis revealed that these compounds display a common topology, with chains composed of alternating [RetVc14（CN）2]2- and [Mn（cyclam）]2＋ （M = Ni in 1, Cu in 2） or [Cull（N,N＇-dimethylcyclam）]2＋ （in 3） building units. Two different chain orientations with a tilt angle of ca. 51° to 55° are present in the crystal packing of these compounds. The magnetic susceptibility measurements suggest the presence of intrachain ferromagnetic interactions between the S = 3/2 ReTM centers and the 3d metal ions： S = 1 Ni1I or S = 1/2 CuII. At low temperature, a three-dimensional ordered magnetic phase induced by interchain antiferromagnetic interactions （antiferromagnetic for 1 and 2; canted antiferromagnetic for 3） is detected for the three compounds.
