2-Amino-6-methyl-5-{5-[(naphthalen-2-yl-oxy)meth-yl]-1,3,4-oxadiazol-2-ylsulfan-yl}-4-(3-nitro-phen-yl)pyridine-3-carbonitrile.

ABSTRACT: The asymmetric unit of the title compound, C26H18N6O4S, contains two independent mol-ecules (A and B). The dihedral angles between the oxadiazole ring and naphthalene ring system are 42.59?(14) and 6.88?(14)?Å in mol-ecules A and B, respectively. The dihedral angles between the pyridine and benzene rings in A and B are 65.53?(13 )and 87.67?(13)?Å, respectively. In the crystal, mol-ecules A and B are linked through a pair of N-H?N hydrogen bonds involving one -NH2 group H atom and second pair of N-H?N hydrogen bonds involving the other -NH2 group H atom, forming an -ABAB- ribbon along [100] containing R 2 (2)(8) and R 2 (2)(12) ring motifs. These ribbons are further connected by weak C-H?N, C-H?O and C-H?? inter-actions, resulting in a three-dimensional network. The crystal studied was a non-merohedral twin with refined components 0.906?(1):0.094?(1).
