Abstract: New coordination complexes {[AgL]X}n (X = BF4-, 1a; X = ClO4-, 1b) and {[Ag(L)2]ClO4}n (2) were synthesized by reactions of corresponding silver(I) salt with new tripodal ligand 3,3'-[3-(1H-imidazol-1-yl)propylazanediyl]dipropanenitrile (L) under ligand to metal ratio of 1:1 and 2:1, respectively, and their structures were determined by single crystal X-ray diffraction, electrospray mass spectrometry. Complexes 1a and 1b have one-dimensional (1D) chain structure while complex 2 is mononuclear one. The results show that the metal to ligand ratio has subtle influence on structure of the complexes.
