Abstract
Abstract
This review covers 17 Pt(II) complexes of the compositions: Pt(ƞ3-N1C1N2)(PL), Pt(ƞ3-S1C1S2)(PL), Pt(ƞ3-S1B1S2)(PL), Pt(ƞ3-S1S2O1)(PL), Pt(ƞ3-O1N1C1)(PL), Pt(ƞ3-O1N1S1)(PL) and Pt(ƞ3-C1N1S1)(PL). These complexes crystallized in three crystal classes: monoclinic (8 examples), triclinic (8 examples) and orthorhombic (1 example). The heterotridentate ligands creates 5 + 5-membered metallocyclic rings (most common) and 5 + 6-membered. The heterotridentate ligands with monodentate P ligands build up a distorted square-planar geometry about Pt(II) atoms. The Pt–L and L–Pt–L were analyzed. The τ
4 parameter which indicate a degree of distortion growing in the sentence: 0.057 Pt(ƞ3-O1N1S1)(PL) < 0.066 Pt(ƞ3-S1C1S2)(PL) < 0.149 Pt(ƞ3-S1S2O1)(PL) < 0.158 Pt(ƞ3-O1N1C1)(PL) < 0.160 Pt(ƞ3-C1N1S1)(PL) < 0.162 Pt(ƞ3-S1B1S2)(PL) < 0.165 Pt(ƞ3-N1C1N2)(PL).
