P. Suman et al., Effect of weak hydrogen bonding and included solvent on the crystal structure of the square-planar complex trans-Pt{PPh2(C16H15)}(2)Cl-2, NEW J CHEM, 22(12), 1998, pp. 1311-1313
Crystallisation of the square-planar complex trans-Pt{PPh2(C16H15)}(2)Cl-2
from dichloromethane-diethyl ether (1:1) affords two different solvates; tr
ans-Pt{PPh2(C16H15)}(2)Cl-2. CH2Cl2 1 and trans-Pt{PPh2(C16H15)}(2)Cl-2. Et
2O 2; the CH2Cl2 forms H-bonding interactions with the complex whereas the
Et2O participates only in weak van der Waals interactions; these difference
s arise from the different hydrogen-bonding characteristics of each solvent
