چکیده
There are two symmetry-independent mol-ecules in the asymmetric unit of the title compound, C(16)H(16)N(2)O, that differ in conformation. The dihedral angles between the benzene rings in the two mol-ecules are 44.35 (19) and 48.14 (17)°, but the rings twist in opposite directions. The acetamide groups make nearly equal dihedral angles of 25.4 (3) and 25.7 (3)° with the parent benzene rings. An S(6) ring motif is formed in each mol-ecule by intra-molecular C-H⋯O close contacts. In the crystal, strong N-H⋯O hydrogen bonds between acetamide groups generate a C(4) chain motif arranging the mol-ecules into two symmetry-independent polymeric structures extending along [010].

The title mol-ecule, C(15)H(16)N(2)O(3)S, has a twisted U-shaped conformation. The twist occurs in the central C-S(=O)(2)N(H)-C unit with the C-S-N-C torsion angle being -58.38 (14)°. The benzene rings lie to the same side of the mol-ecule and form a dihedral angle of 67.03 (10)°. The crystal packing features N-H⋯O hydrogen bonding, which leads to supra-molecular chains with a tubular topology ...

The structure of the title compound, [Cd(3)Cl(6)(C(15)H(15)NO(2))(2)(CH(4)O)(2)](n), is based on a layered zigzag polymeric chain along the c axis. The Cd(II) ions are linked by double chlorine bridges alternating between one CdCl(4)(CH(3)OH)(2) and two CdCl(4)(C(15)H(15)NO(2)) octa-hedral coordination units. Additional intrachain N-H⋯O and O-H⋯Cl hydrogen-bond interactions stabilize this arran...
