The title compound, [Ni(NCS)(2)H2N(CH2)(3)NH2}(2)], (I), is an octahedral complex of nickel(II) in which the thiocyanate ligands are bonded through nitrogen in a cis arrangement, while the 1,3-propanediamine ligands are N,N'-bidentate. The molecule lies on a crystallographic twofold axis. The coordination geometry about the metal deviates only slightly from ideal [Ni-N distance range 2.118 (3)-2.143 (3)Angstrom, cis-N-Ni-N angle range 85.9 (1)-95.3 (1)degrees and trans-N-Ni-N angle range 171.9(1)-178.3 (3)degrees]. The molecules pack in a non-centrosymmetric arrangement and have been determined to possess the Lambda configuration. The structural features of (I) are compared to those of related N-substituted 1,3-propanediamine complexes.
