| Abstract |
A novel heterometallic tetranuclear complex [Cr(3)Cd(NCS)(4)(H(2)tea)(Htea)(3)]center dot 3CH(3)OH (1) has been prepared using cadmium oxide, Reinecke s salt, ammonium thiocyanate and a methanol solution of triethanolamine (H(3)tea) in air. Crystallographic investigations reveal that the molecular structure of the complex is based on an uncommon asymmetric \Cr(3)Cd(mu(3)-O)(2)(mu-O)(4)\ core with firstly observed terminal coordination of the NCS-groups in such molecular structure type. A network of O-H center dot center dot center dot O hydrogen bonds as well as S center dot center dot center dot S interactions link the molecules into a two-dimensional supramolecular network. Variable-temperature (1.8-300 K) magnetic susceptibility measurements show a change of the mu(B) value at low temperature, indicative of antiferromagnetic interactions (J = -7.45 cm(-1)) between chromium(III) centers. |
