Abstract
Abstract
This review covers almost 30 Pt(II) complexes of the composition Pt(η3-P1X1P2)(Y), (X1 = BL, SL, or SiL), (Y = H, OL, NL, CL, Cl, PL, or I) and Pt(η3-P1P2Si1)(CH3). Heterotridentate ligands form six types of metallocyclic rings: P1CNB1NCP2, P1C2S1C2P2, P1C2Si1C2P2, (most common), P1CNSi1NCP2, and P1C3Si1C3P2 with common B1, S1, or Si1 atoms. In P1C2P2C3Si1 the P2 atom is common. The structural data (Pt–L, L–Pt–L) are analyzed and discussed with an attention to the distortion of a square-planar geometry about Pt(II) atoms as well as trans-influence. The sum of Pt–L(x4) bond distances growing with covalent radius of the X1 and Y atoms.
