2-Methoxy-N-[(S)-3-methylbutan-2-yl]-6-{[(S)-3-methylbutan-2-yl]amino}-3,5-dinitrobenzamide
The title compound, C(18)H(28)N(4)O(6), crystallizes with two mol-ecules in the asymmetric unit which differ slightly in conformation. The dihedral angle between the amide plane and the benzene ring are 72.6 (2) and 66.8 (2)° in the two mol-ecules. A strong intra-molecular N-H⋯O hydrogen bond between the amino and nitro groups occurs in each mol-ecule. The crystal structure features two symmetr...

The title compound, [Zn(C(15)H(14)N(3)S(2))(2)], contains two chemically equivalent Schiff base anions that are coordinated to the Zn(II) ion as tridentate N,N',S-chelating ligands, creating a distorted octa-hedral environment [the smallest angle being 75.40 (6)° and the widest angle being 162.87 (6)°], with the two S atoms in cis positions. The dihedral angle between the mean planes of the two...

The title compound, C(13)H(11)NO(4)·H(2)O, is a monohydrate of a betaine exhibiting a positively charged N-substituted isoquino-line group and a deprotonated carboxyl group. In the crystal, mol-ecules are connected via short O-H⋯O hydrogen bonds between protonated and deprotonated carboxyl groups into chains of either R or S enanti-omers along [001]. These chains are additionally connected by h...
