LOW-TEMPERATURE MAGNETIC-PROPERTIES AND MOLECULAR-STRUCTURE OF CU(2,2'-BIPYRIDINE)2(NCS)2

The temperature and field dependence of the magnetic susceptibility of Cu(2,2′-bipyridine)2(NCS)2 have been determined over the range 2-100 K using the Faraday method. The magnetic results in conjunction with IR spectra are inconsistent with a previous formulation of the compound as a thiocyanate bridged dimer but rather support a monomeric pseudo-octahedral structure, [Cu(2,2′-bipyridine)2(NCS)2], containing magnetically isolated cupric ions exhibiting essentially Curie law behavior. © 1979.
