Aslanov The crystal and molecular structure of cis-bis(cyclohexanon-thiosemicarbazonato-N,S)nickel (II) Abstract The X-ray single-crystal diffraction study of cis-bis(cyclohexanon-thiosemicarbazonato-N,S)nickel (II) chelate complex has been carried out. As a result of intramolecular steric tensions, the [NiN2S2] coordination center is non-planar; the deviations of S and N atoms from the least-squares plane are 0,360 and 0,383 Ǻ, respectively. The molecules are linked into layers by N-H...N hydrogen bonds. The predominant formation of cis isomer is in accordance with the results of DFT calculations.
