The crystal structure of the complex [Ni(pz(2)thCH)(2)(O(O')NO '')]NO3
has been determined by X-ray diffraction, where pz and th represent t
he pyrazolyl and thienyl groups of a potentially tripodal ligand. The
thienyl groups are not bound to the metal, which is coordinated to fou
r pyrazolyl groups and a chelating nitrate ion. The electronic 'd-d' t
ransition energies are interpreted in terms of angular-overlap bonding
parameters which agree well with those reported for other similar com
plexes.
