Platinum(II) complexes of 2-(dimethylamino)ethylselenolate - donor-acceptor inter-ligand interactions as evident from experimental and TD-DFT computational analysis
Several platinum(II) complexes of 2-(dimethylamino)ethaneselenolate [PtCl(SeCH2CH2NMe2)(PR3)] (1), [PtPh(SeCH2CH2NMe2)(PBu3)] (2), [Pt2Ph2(Cl)(SeCH2CH2NMe2)(PBu3)2] (3), [Pt2Cl3(SeCH2CH2NMe2)(PR3)2] (4), [Pt(SeCH2CH2NMe2)2(P-P)] (5), [Pt2(SeCH2CH2NMe2)2(P-P)2]++ (6), and [Pt(SeCH2CH2NMe2)(PPh3)]n[PF6]n (7) were synthesized and characterized by elemental anal., UV/visible and NMR (1H, 31P, 77Se, 195Pt) spectroscopy. The stereochem. of these complexes (1-7) was deduced from NMR spectroscopic data. A weak absorption in the UV/visible spectrum of 1 was assigned to a ligand (Se)-to-ligand (PR3) charge transfer (LLCT), supported by TD-DFT calcns. The structures of [PtCl(SeCH2CH2NMe2)(PPh3)] and [Pt2Ph2(Cl)(SeCH2CH2NMe2)(PBu3)2] were established by single crystal x-ray diffraction anal. Each platinum atom in the latter is coordinated to four different ligands and Me2NCH2CH2Se behaves as m2-bridging and is also simultaneously chelated to one of the platinum atoms. [on SciFinder(R)]
