Organomonophosphines in Pt(η3-X1X2X3)(PR3), (X = N1, N2, N3; S1, S2, S3; or Te1, Te2, Te3) Derivatives: Structural Aspects

This paper covers nineteen Pt(II) complexes of the composition Pt(η3-X1X2X3)(PR3), (X = N1, N2, N3; S1, S2, S3; or Te1, Te2, Te3). These crystallized in three crystal classes: triclinic (eleven examples), monoclinic (six and orthorhombic (two examples). Each tridentate ligand creates two metallocyclic rings with common Te2 donor ligands types N1C2N2C2N3, N1C2N2NC2N3, S1C2S2C2S3, S1C3S2C3S3, Te1CNTe2NCTe3. The homotridentate monodentate PR3 builds up a distorted square planar geometry about atoms. degree distortion ranges from 0.029 to 0.092, reason for is discussed. There an example that contains crystallographically independent molecules within same crystal. classic isomerism.
