Sumario:The title Sn(IV) complex, [Sn(C(6)H(5))(3)Cl(C(18)H(15)O(4)P)], is a formal adduct between triphenyl phosphate (PhO)(3)P=O and the stannane derivative chlorido­tri­phenyl­tin, SnPh(3)Cl. The structure refinement reveals that this mol­ecule displays the largest Sn—O bond length for compounds including the X=O→SnPh(3)Cl 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 inter­basin 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)(3)P=O and SnPh(3)Cl moieties.
