Novel pyrazolate-bridged dinuclear Pd(II) diimine complexes that bind inorganic anions

Pyrazolate-bridged dinuclear Pd(II) diimine complexes with clip-like cavities that bind anions have been synthesized through metal-metal interaction and spontaneous deprotonation from 1H-3,5-diphenylpyrazole (HL) in aqueous solution.
