Synthesis and molecular structure of [{Pd2(CH2C6H4P(o-tolyl)2-κC,P)2(μ3-3,5-dmpz-N,N′,C4)2Ag(μ-ClO4)}2] (3,5-dmpz = 3,5-dimethylpyrazolato), a silver derivative showing unprecedented η1-azolato coordination

The reaction of [Pd2(CH2C6H4P(o-tolyl)2-κC,P)2(µ-3,5-dmpz)2] (1) with AgClO4 renders [{Pd2(CH2C6H4P(o-tolyl)2-κC,P)2(µ3-3,5-dmpz-N,N′,C4)2Ag(η2-µ-ClO4)}2] (2), a palladium–silver derivative displaying an unprecedented dmpz bridging ligand η1 bonded to the Ag centers, involving only the C4 atom of each dmpz ligand.
