In the title compound, C(13)H(12)N(2)O(3), the dihedral angle between the aromatic rings is 7.94 (12)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(6) loops. Weak π-π [centroid-centroid separations = 3.7480 (13) and 3.9047 (13) Å] and C-H⋯π inter-actions help to consolidate the packing.

In the crystal structure of the title compound, [Cu(2)Br(2)(C(9)H(14)N(2)S)(2)], the mol-ecule resides about a crystallographic inversion center. The coordination sphere around each copper ion has a distorted tetra-hedral geometry, with ligation by two bridging bromide ions, an amine N atom and an imine N atom. The thio-phene ring is disordered over two sites, with occupancies of 0.719 (3) and ...
