摘要:
The silver(I) complexes of 2-(3-pyridyl)benzimidazole (PyBLm) [Ag-2(PyBIm)(2)](A)(2) (A=ClO4- (1) and CF3SO3- (2)) were prepared and the structures characterized by X-ray crystallography. The networks of the dinuclear complexes are extended via weak interactions between the cations and anions and controlled by the latter. Each cation in both complexes has the Ag atoms bridged by two PyBIm ligands via the N-py and N-Blm donor atoms in quasi-linear geometry. The 1D-chain (1) and 2D-sheet (2) structures were further constructed via intermolecular Ag ... O, Ag ... F and NH ... O interactions. (C) 1999 Elsevier Science S.A, All rights reserved.
