Abstract: | The complexes Me2Au(R2pz) (R = H, Me; pzH = pyrazole) are formed on reaction of dimethylgold(III) nitrate with 3,5-disubstituted pyrazoles, R2pzH, in water, but a similar procedure with Ph2pzH followed by recrystallization from CHCl3/CCl4 gives [Me2Au(Ph2pzH)2]NO3 · ca.CCl4. The complexes Me2(Ph2pz) (M = Au, Tl), Me2In(Ph2pz)·CH2Cl2, and Me2Tl(Me2pz) are formed on reaction of Me2MI (M = Au, Tl) or Me2InCl with Ag(R2pz) in nonaqueous solvents. The complexes Me2Au(R2pz) (R = H, Me, Ph) are dimeric in chloroform and Me2Tl(Me2pz) is dimeric in benzene, but osmometric data for Me2Tl(Ph2pz) in benzene indicate presence of a monomer—dimer equilibrium. |
