Issue Date: | 1-Jan-2006 | Journal: | Acta Crystallographica Section C: Crystal Structure Communications | Abstract: | The title compound, [Ni(C 28 H 30 N 3 O 2 PS)], crystallizes with two independent molecules in the asymmetric unit. The Ni II atoms are in significantly deformed square-planar environments formed by an ONNP donor set from a thiosemicarbazide-based tetradentate ligand. The Ni II atom and the ONN donor atoms are nearly coplanar, while the P atom deviates from their mean planes by 0.278 (4) and 0.202 (4) A for the two independent molecules. The P-containing chelate rings are remarkably non-planar, adopting a boat conformation, which is unusual for chelate rings in transition metal complexes with thiosemicarbazide-based tetradentate ligands. The orientation of the ethoxy group bonded to this chelate ring is caused by an intramolecular C-H⋯μ interaction with the opposing phenyl ring. There are no hydrogen bonds; instead, numerous intermolecular C-H⋯μ interactions dominate in the crystal packing. © 2006 International Union of Crystallography. | URI: | https://open.uns.ac.rs/handle/123456789/11070 | ISSN: | 01082701 | DOI: | 10.1107/S0108270106018932 |
