• The formation of ternary (2,2′-bipyridine)thiocyanatocadmium(II) complexes has been studied by calorimetry in <I>N</I>,<I>N</I>-dimethylformamide containing 0.4 mol dm<SUP>−3</SUP> (C<SUB>2</SUB>H<SUB>5</SUB>)<SUB>4</SUB>NClO<SUB>4</SUB> as a constant ionic medium at 25 °C. The formation of [CdA(bpy)]<SUP>+</SUP>, [CdA<SUB>2</SUB>(bpy)], [CdA<SUB>3</SUB>(bpy)]<SUP>−</SUP>, [CdA(bpy)<SUB>2</SUB>]<SUP>+</SUP>, and [CdA<SUB>2</SUB>(bpy)<SUB>2</SUB>] (A=SCN, bpy=2,2-bipyridine) is revealed, and their formation constants, enthalpies, and entropies were obtained. The result is compared with that in the corresponding halide systems in the same solvent.
