摘要：

The syntheses of dark-green diamagnetic complexes [Ni(H(2)L)]X (H(2)L = the monoanion of pentane-2,4-dionebis(thiosemicarbazone) and X is either NO3 or NCS) and the crystal structure of the NCS complex is described. Crystals of the NCS complex are monoclinic, space group C2/c, with a = 11.867(1), b = 10.715(1), c = 22.319(1) Angstrom, beta = 90.11(1)degrees, V = 2838.0(4) Angstrom(3), Z = 8. The crystal structure was refined using 2491 independent reflections to R = 0.051, The structure consists of well separated [Ni(H(2)L)](+) cations and NCS- anions. Ni-II has a slightly distorted square-planar geometry formed with two nitrogen (Ni-N = 1.863(4) and 1.856(4) Angstrom) and two sulphur atoms (Ni-S = 2.153(2) and 2.163(1) Angstrom) of the monodeprotonated tetradentate ligand.
