The title complex [AgL(NO3)]2 1, where L = 2-acetamido-5-methyl-1,3,4-thia- diazole, was prepared from the reaction of 2-acetamido-5-methyl-1,3,4-thiadiazole with AgNO3 at room temperature and its structure has been determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/c with a = 12.5454(8), b = 11.9672(12), c = 6.8925(6) ?, β = 98.468(2)°. V = 1023.51(15) ?3, Mr = 327.08, Dc = 2.123 g/cm3, Z = 4, μ(MoKα) = 2.174 mm–1, F(000) = 640, R = 0.0259 and wR = 0.0580 for 1787 observed reflections with I > 2σ(I). Complex 1 self-assembls into a quasi-three-dimensional network consisting of adjacent dimers through inter- molecular Ag???O weak interactions.
