A Lewis-basic, dionio-substituted phosphane.
Bis{guanidine} H(2)C{hpp}(2)[hppH = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine] reacts with PPhCl(2) to generate the dionio-substituted phosphane, [H(2)C{hpp}(2)PPh](2+)[Cl](-)(2) which, despite the formally dicationic phosphorus centre, forms an unprecedented coordination compound with platinum.
