(prepared in situ by the reaction between NaH, Hpz, and SOCl2 in THF) and C6H4[C(O)(2-py)]2 in THF catalyzed by CoCl2 yields m-C6H4[C(pz)2(2-py)]2 (1, pz= pyrazolyl, py=pyridyl) in moderate yield, along with 1-[C(pz)2(2-py)]-4-[C(O)(2-py)]C6H4. The potentially bitopic ligand 1 reacts with AgPF6 to yield [Ag(1)2](PF)6 (3), regardless of the stoichiometry of reagents used in the preparation. X-ray structural
