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.
