This manuscript summarizes and analyzes X-ray data of monomeric cis-PtP 2 CCl derivatives. These complexes crystallize in the following crystal systems: tetragonal, P4 2 /n (3), triclinic, Pī (10), orthorhombic, P2 1 2 1 2 1 (prevails)(16), and monoclinic, P2 1 /c (prevails) (36) examples. There are three subgroups of the respective complexes: Pt(η 1-PL) 2 (η 1-CL)(η 1-Cl); Pt(η 2-P 2 L)(η 1-CL)(η 1-Cl) and Pt(η 1-PL)(η 2-P,CL)(η 1-Cl). The chelating P,P-donor ligands form: four-(POP, PCP), five-(PC 2 P), six-(PC 3 P, PCNCP), seven-(PC 4 P) and even ten-(PCNCNCNCP) membered rings. The chelating P.C-donor ligands create three-(PC), four-(PCC) and five-(PC 2 C) membered rings. The mean Pt-L bond distance elongates in the sequence: 2.10 Å (C, trans to P) < 2.222 Å (P, trans to Cl) < 2.312 Å (P, trans to C) < 2.360 Å (Cl, trans to P). There are examples which exist in two isomeric forms, of the distortion isomer type.
