The synthesis of a pyrazol-3-ylidene palladium complex is described, and results of a single-crystal X-ray diffraction study are presented. The properties of pyrazolium salts as well as of two types of heterocyclic mesomeric betaines, the pseudo-cross-conjugated mesomeric betaine pyrazolium-3- carboxylate and its cross-conjugated analog pyrazolium-4-carboxylate, are compared.
