Can weak interactions modify the binding properties of a strong nitrogen donor? Unusual N-coordination of a phosphoranylidene-substituted pyrazolone unit towards palladium(ii) centres: an experimental and theoretical study
Abstract
Selective N(2)-binding of 3-methyl-1-phenyl-4-(triphenylphosphoranylidene)-2-pyrazolin-5-one (L) has been found in two palladium(II) complexes, [PdCl2L2]
(2) and [Pd(o-C6H4CH2NMe2)ClL]
(3).
