In the complex [Cd(NCS)(2)(C7H18N2)(2)], the Cd atom lies on an inversion centre and has a distorted octahedral environment consisting of four amine N atoms from two bidentate N-1-isopropyl-2-methylpropane-1,2-diamine (N-N) ligands [Cd-N(primary) = 2.362(3) Angstrom, Cd-N(secondary) = 2,400(3) Angstrom] and two N atoms from two isothiocyanato groups [Cd-N = 2.378(5) Angstrom]. The conformation of the diamine chelate rings is delta lambda. Molecules are linked by N-H ... S hydrogen bonds(N ... S 3.665 Angstrom.
