Synthesis and characterisation of new binuclear complexes containing a relatively strong Pt to Hg donor bond. Molecular structure of complex [Pt(C^P)(μ-O2CCH3)2Hg(O2CCH3)]
Abstract
[{Pt(C^P)(μ-O2CCH3)}2]
(1A)
(C^P = CH2-C6H4-P(o-tolyl)2-κC,P) reacts with Hg(O2CCH3)2 and [{Pt(C^P)(μ-O2CCF3)}2]
(1B) reacts with Hg(O2CCF3)2 in a 1 ∶ 2 molar ratio to afford the neutral complexes [Pt(C^P)(μ-O2CCH3)2Hg(O2CCH3)]
(2) and [Pt(C^P)(μ-O2CCF3)2Hg(O2CCF3)]
(3) respectively. They also react with equimolar amounts of HgX2
(X = Cl, Br, I) to give mixtures of the corresponding neutral complexes [Pt(C^P)(μ-O2CR)2HgX]
(R = CH3, X = Cl 4, Br 5, I 6; R = CF3, X = Cl 7, Br 8, I 9) and [{Pt(C^P)(μ-X)}2]
(X = Cl, Br, I). Complexes 4–6 could be isolated from the mixtures as pure samples but complexes 7–9 could not. Complexes [Pt(C^P)(μ-O2CR)2HgX]
(R = CH3, X = Cl 4, Br 5, I 6; R = CF3, X = Cl 7, Br 8, I 9) can also be prepared by treatment of the carboxylate derivatives [Pt(C^P)(μ-O2CR)2Hg(O2CR)]
(R = CH32, CF33) with
