The 4JPtH coupling constant in platinum–hydrazone complexes: relative magnitude of the coupling constant between an alkyl group and a metal atom which are mutually cis- and trans- with respect to the azomethine double bond
Abstract
The coupling constant between the alkyl protons and the platinum nucleus in [Pt(C2H4)Cl2(R1R2C : N·NR3R4)] complexes is higher when the alkyl group is cis- to the metal, with respect to the azomethine double bond, than when it is trans- to it.
