Synthesis, Characterization, and Crystal Structure of a Diorganotin(IV)‎ Complex with 2-Oxo-2-Phenylacetic Acid 4-Hydroxybenzohydrazone

الملخص EN

The complex dibutyltin 2-oxo-2-phenylacetic acid 4-hydroxybenzohydrazone has been synthesized and characterized by elemental analysis, IR, 1H and 13C NMR, and X-ray single-crystal diffraction studies.

The crystal structure belongs to triclinic, space group P-1 with a=9.3220 (10) Å, b=9.8779 (11) Å, c=15.9401 (17) Å, β=97.0930 (10)∘, Z=2, V=1427.6(3) Å3, Dc=1.413 mg/cm3, μ=0.936 mm−1, F(000)=628, R=0.1158, and wR=0.2522.

X-ray analysis indicates that O(2), N(2), O(4), and O(4)#1 from the ligand and O(5) from ethanol molecule are in the equatorial positions; the axial positions are occupied by two n-butyl groups.

It shows a distorted pentagonal bipyramid configuration with seven-coordination for central tin atom.

Fascinatingly, the supramolecular infrastructures are observed, which exist as two-dimensional sheets assembled from the organometallic subunits through intermolecular and intramolecular O–H⋯X or C–H⋯X (X = O or N) hydrogen bonds.
