Effect of weak hydrogen bonding and included solvent on the crystal structure of the square-planar complex trans-Pt{PPh2(C16H15)}2Cl2

Abstract

Crystallisation of the square-planar complex trans-Pt{PPh₂(C₁₆H₁₅)}₂Cl₂ from dichloromethane–diethyl ether (1:1) affords two different solvates; trans-Pt{PPh₂(C₁₆H₁₅)}₂Cl₂·CH₂Cl₂1 and trans-Pt{PPh₂(C₁₆H₁₅)}₂Cl₂·Et₂O 2; the CH₂Cl₂ forms H-bonding interactions with the complex whereas the Et₂O participates only in weak van der Waals interactions; these differences arise from the different hydrogen- bonding characteristics of each solvent.
