Abstract
AbstractTwo novel metal‐organic coordination complexes of copper(II) and silver(I) with 1,3,4‐thiadiazole‐based ligands HL1 [N‐(5‐methyl‐1,3,4‐thiadiazol‐2‐yl)‐4‐pyridinecarboxamide] and H2L2 [2,5‐dipropanoylamino‐1,3,4‐thiadiazole] have been synthesized in diffusion conditions and characterized by elemental analysis, IR spectroscopy and single‐crystal X‐ray diffraction analysis. The X‐ray crystal structural determinations show that complex [Cu2(L1)2(BF4)(OH)]∞ (1) is a three‐dimensional (3‐D) framework containing channels along the c axis, and the channels' inner surface decorated by S atom. Complex [Ag2(H2L2)2(HL2)(PF6)]∞ (2) shows a one‐dimensional chain comprising two five‐coordinated silver centers which form dinuclear structure units. The AgṁṁṁAg weak interactions were observed between the two non‐bonding silver atoms in the dinuclear unit.
