Synthesis, Characterization and Crystal Structure of a Dinuclear Silver(I) Complex: [AgL(NO_3)]_2 (L= 2-Acetamido-5-methyl-1,3,4-thiadiazole)

1INTRODUCTION There has been great interest in supramolecular tran-sition metal chemistry since self-assembly through coor-dinate bond formation has proven to be powerful tool for constructing rings,polymers and networks.Some of these compounds have potential uses in the context of molecular recognition,catalysis,size-selective guest transportation,optical materials,molecular magne-tism,semiconductors and conductors1~4].Organic ami-des have proved to be useful in self-assembly through int…

Synthesis, Characterization and Crystal Structure of a Dinuclear Silver(I) Complex:[AgL(NO3)]2(L=2-Acetamido-5-methyl-1,3,4-thiadiazole)

The title complexAgL(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)(A), β = 98.468(2)°. V = 1023.51(15) (A)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.
