| Summary: | Two independent molecules comprise the asymmetric unit of
the title compound, [Sn(C4H9)(C13H12N3O)Cl2]. The Sn atom
in each is coordinated by the tridentate ligand via the
phenoxide O, hydrazine N and pyridyl N atoms, forming fiveand six-membered chelate rings. The approximately octahedral coordination geometry is completed by the -C atom of the n-butyl group (which is trans to the hydrazine N atom) and two mutually trans Cl atoms. Differences between the molecules are evident in the relative planarity of the chelate rings and in the conformations of the n-butyl groups [C—C—C—C = 177.2 (5) and 64.4 (11)]. Significant differences in the Sn—Cl bond lengths are related to the formation of N—H���Cl hydrogen bonds, which link the molecules comprising the asymmetric unit into dimeric aggregates. These are consolidated in the crystal packing by C—H���Cl contacts. The structure was refined as an inversion twin; the minor twin component is 37 (3)%. |
