Table 2. Selection of geometrical parameters of the PtII coordination sphere of 1 and two solvates of [PtCl2(PPh3)2] (Miao et al., 2009 ▸; Al-Fawaz et al., 2004 ▸) representing the uncaged phosphines; discrepancies from planarity can be detected using the τ4 parameter (Yang et al., 2007 ▸) and the dihedral angle φ between Pt1/P1/P2 and Pt1/Cl1/Cl2.
