چکیده
Planar mol-ecules of the title compound, C(3)H(4)N(4)O, are organized into sheets by extensive N-H⋯O and N-H⋯N hydrogen bonding in the (101) plane of the crystal structure. These hydrogen bonds may also stabilize the mol-ecule in the Z form. The title compound is in the amide form, as shown by the C=O bond length [1.252 (2) Å].

The reaction of silver nitrate and cafenstrole (N,N-diethyl-3-mesitylsulfonyl-1H-1,2,4-triazole-1-carboxamide), a triazole herbicide, leads to the title coordination polymer, [Ag(NO3)(C16H22N4O3S)] n , whose asymmetric unit comprises one cafenstrole ligand mol-ecule, one AgI atom and one nitrate ion. The AgI atom, with a distorted trigonal-pyramidal environment, is coordinated by one nitro-gen ...
