This review covers over one hundred Pt(II) complexes of the compositions Pt(η3–P1X1P2)(Y), (X1 = O1L, N1L, C1L, B1L, S1L or Si1L) and (Y = H, F, Cl, Br, I, O2L, N2L, C2L, or P3L). These complexes crystallized in five crystal classes: monoclinic (60 examples), triclinic (36 examples), orthorhombic (13 examples), trigonal (1 example) and tetragonal (1 example). Each heterotridentate organodiphosphine creates two metallocyclic rings with a common X1 atom. There are fourteen types of metallocycles from which the P1C2X1C2P2 is most common. The structural parameters (Pt-L, L-Pt-L) are analyzed and discussed with attention to the distortion of a square-planar geometry about the Pt(II) atoms as well as of trans-influence.
