Dinuclear silver(Ⅰ) complex [Ag~2(hpb)(ClO~4)~2(acetone)~2]1, (hpb=hexaphenylbenzene) and the single crystal of the free ligand [hpb] 2 were synthesized in polar solvent of acetone, and their crystal structures have been determined by single-crystal X-ray diffraction. While the free ligand 2 exhibited an asymmetric propeller topology with the dihedral angles between the planar phenyl ring and the central ring ranging from 67° to 90°, complex 1 displayed a centrosymmetric dinuclear architecture with the dihedral angles varying from 81° to 86°. By comparing these two compounds together with the other organosilver(Ⅰ) complexes in the hpb family published previously, it is revealed that the molecular architectures of the coordinated complexes is not only anion-dependent, but also being controlled by the type of solvent (polar or non-polar). Furthermore, the configuration and packing-pattern of the free ligand in its solid state are also key factors to dictate and control the structural features of the coordinated complexes. On the other hand, with the varied coordination topologies, a different conductive property can be obtained.
