نویسنده
چکیده
The title compound, C(16)H(16)N(2)O(5)S, is a potent new fungicide. There are two mol-ecules in the asymmetric unit which are linked by C-H⋯π inter-actions, forming a dimer. The two phenyl rings in each mol-ecules are almost coplanar, with C-N-C-C torsion angles of 177.6 (2) and -172.5 (2)°. There are inter-molecular and intra-molecular N-H⋯O hydrogen bonds in the crystal structure.

In the crystal of the title complex, [Cu(C7H6NO4S)2(C6H6N2O)2(H2O)], the CuII cation and the O atom of the coordinated water mol-ecule reside on a twofold rotation axis. The CuII ion is coordinated by two carboxyl-ate O atoms of the two symmetry-related 4-sulfamoylbenzoate (SB) anions and by two N atoms of the two symmetry-related nicotinamide (NA) mol-ecules at distances of 1.978 (2) and 2.025...
