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

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.
