Solid-state thermal reactions of <I>trans</I>- and <I>cis</I>-[Cr(NCS)<SUB>2</SUB>(AA)<SUB>2</SUB>]SCN where AA is 1,2-ethanediamine (en) or 1,3-propanediamine (tn) were studied. Upon heating, both the cis- and trans-complexes lost half mole of diamine to convert into the double complex <I>trans</I>-[Cr(NCS)<SUB>2</SUB>(AA)<SUB>2</SUB>][Cr(NCS)<SUB>4</SUB>(AA)]. The anion moiety [Cr(NCS)<SUB>4</SUB>(AA)]<SUP>−</SUP> was isolated from the double complex. The thermal reactions are thus useful for easy preparation of [Cr(NCS)<SUB>4</SUB>(AA)]<SUP>−</SUP> complex, which has previously been obtained with difficulty from solution reactions.
