| Abstract: | Reaction of 4,4′-di(3-pyridyl-4-pyrimidinyl) disulfide (3-PPDS) with AgNO3 leads to a unique 2D extended structure {Ag(3-PPDS)(NO3)]}n (1) based on Ag2(3-PPDS)2] macrocycle units, of which 1D inorganic Ag(NO3)]n helical chains are generated. By contrast, definite Ag-S bonding interactions associated with the disulfide function have been established in {Ag(2-PPDS)]ClO4}n (2), which is assembled of 4,4′-di(2-pyridyl-4-pyrimidinyl) disulfide (2-PPDS) with AgClO4. Solid state luminescent properties of complexes 1 and 2 are also examined. |
