Synthesis, characterization and X-ray crystal structure determination of cyclopalladated [Csp2,N,N′]−, zwitterionic and chelated compounds in the reaction of 3,5-diphenyl-N-alkylaminopyrazole derived ligands with Pd(II)

In this paper is described the synthesis and characterization of three types of compounds, cyclopalladated, zwitterionic and chelated, which are obtained in a one pot but two steps reaction. X-ray crystal structures of three compounds are presented.
