Abstract: | Ag(NH3)2]+ ions are chosen as an initial reaction precursor because of its simple displacement reaction and intrinsic arrangement as well as specific coordination directionality. Two new silver(I) ammine complexes, Ag2(NH3)HL2 ( 2 ) and Ag2(NH3)2HL3 ( 3 ), were obtained by a simple substitution reaction between Ag(NH3)2]+ ions and pyridine‐4,5‐imidazoledicarboxylic acid H3L2 = 2‐(3′‐pyridyl) 4,5‐imidazoledicarboxylic acid and H3L3 = 2‐(4′‐pyridyl) 4,5‐imidazoledicarboxylic acid]. Silver dimers are connected into a 2D layer and 1D chain in complexes 2 and 3 , respectively. In complex 2 two kinds of displacement reactions (mono‐substituting and bis‐substituting) occurred between the ammine molecules in Ag(NH3)2]+ ions and H3L2, however, only the mono‐substituting reaction occurs in complex 3 . |
