Three new cyanido-bridged heterometallic Re IVNi II and Re IVCu II 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 [Re IVCl 4(CN) 2] 2- and [M II(cyclam)] 2+ (M = Ni in 1, Cu in 2) or [Cu II(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 Re IV centers and the 3d metal ions: S = 1 Ni II or S = 1/2 Cu II. 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.
