Study of Pt(II)-cyclic amines complexes of the types cis- and trans-Pt(amine)2I2 and cis- and trans-Pt(amine)2(NO3)2 and their aqueous products by

摘要: Abstract Complexes of the types cis - and trans -Pt(amine) 2 I containing cyclic amines were synthesized studied mainly by IR multinuclear NMR spectroscopies. The compounds converted to (NO 3 ) , which also investigated. hydrolysis aquation reactions latter then in D O different conditions pH. In acidic medium, aqueous product is [Pt(amine) (D O) ] 2+ for a few amines, O)(NO )] + was detected. basic pH, main Pt(amine) (OD) (OD)(NO detected several compounds. neutral isomers form between two four species fresh solutions. most shielded 195 Pt monoaqua–monohydroxo complex -[Pt(amine) O)(OD)] less compound dihydroxo-bridged dimer (μ-OD) observed all For monohydroxo-bridged [Pt(D O)(amine) (μ-OD)Pt(OD)(amine) cyclohexylamine, fourth signal assigned hydroxo-bridged trimer [(Pt(amine) (μ-OD)) 3+ . spectroscopy has shown that concentration monomer decreases with time, while dimers increases. Only one 13 C 1 H spectra complexes measured. All coupling constants 2,3 J ( Pt– H) C) are larger than isomers.
