Several platinum(II) complexes of 2-(dimethylamino)ethaneselenolate with the formulae, [PtCl(SeCH2CH2NMe2)(PR3)] (1), [PtPh(SeCH2CH2NMe2)(PnBu3)] (2), [Pt2Ph2(Cl)(SeCH2-CH2NMe 2)(PnBu3)2] (3), [Pt2Cl3(SeCH2CH2NMe 2)(PR3)2] (4), [Pt (SeCH2CH2NMe2)2(P-P)] (5), [Pt2(SeCH2CH2NMe2)2- (P-P)2]++ (6), and [Pt(SeCH2CH2NMe2)(PPh3)] n[PF6]n (7) have been synthesized and characterized by elemental analysis, UV/Vis and NMR (1H, 31P, 77Se, 195Pt) spectroscopy. The stereochemistry of these complexes (1-7) has been deduced from NMR spectroscopic data. A weak absorption in the UV/Vis spectrum of 1 has been assigned to a ligand (Se)-to-ligand (PR3) charge transfer (LLCT), supported by TD-DFT calculations. The structures of [PtCl(SeCH2CH2NMe2)(PPh3)] and [Pt2Ph2(Cl)(SeCH2CH2NMe 2)(PnBu3)2] have been established by single crystal X-ray diffraction analysis. Each platinum atom in the latter is coordinated to four different ligands and Me2NCH2CH2Se behaves as μ2-bridging and is also simultaneously chelated to one of the platinum atoms.
