摘要：

Convergent preparative routes to new urea-pyrazolate dinucleating ligands are described. Metal complexes of these ligands have hydrogen bond donors that are proximal to the metal centers that interact with other coordinated species. This is exemplified by Co-II dimers with Co-II-mu-Cl-Co-II motifs, in which the chloro ligand is involved in four intramolecular hydrogen bonds, These noncovalent interactions appear to influence the Coll-Cl bonds, which are unusually long, having lengths greater than 2.5 angstrom.
