Abstract
The title SnIV complex, [Sn(C6H5)3Cl(C18H15O4P)], is a formal adduct between triphenyl phosphate (PhO)3P=O and the stannane derivative chlorido-tri-phenyl-tin, SnPh3Cl. The structure refinement reveals that this mol-ecule displays the largest Sn-O bond length for compounds including the X=O→SnPh3Cl fragment (X = P, S, C, or V), 2.6644 (17) Å. However, an AIM topology analysis based on the wavefunction calculated from the refined X-ray structure shows the presence of a bond critical point (3,-1), lying on the inter-basin surface separating the coordinated phosphate O atom and the Sn atom. This study thus shows that an actual polar covalent bond is formed between (PhO)3P=O and SnPh3Cl moieties.
