Synthesis, characterisation and coordination chemistry of a new multidentate P2N4 ligand system.
A new potentially hexadentate P(2)N(4) ligand has been prepared and its coordination chemistry to Pd(II) and Pt(II) investigated. The ligand bonds in a chelating fashion via the diphosphine backbone to PdCl(2) and PtCl(2) while the appended pyridyl groups remain non-bonding. Abstraction of the chloride ions from the platinum complex results in fluxional exchange of the pyridyl groups in solution at room temperature on the NMR timescale. X-ray crystallographic analysis of this platinum complex revealed a tetracoordinate complex with two bound and two free pyridyl arms.
