2-Amino-6-methyl-5-{5-[(naphthalen-2-yl­oxy)meth­yl]-1,3,4-oxadiazol-2-ylsulfan­yl}-4-(3-nitro­phen­yl)pyridine-3-carbonitrile

The asymmetric unit of the title compound, C(26)H(18)N(6)O(4)S, contains two independent mol­ecules (A and B). The dihedral angles between the oxadiazole ring and naphthalene ring system are 42.59 (14) and 6.88 (14) Å in mol­ecules 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, mol­ecules A and B are linked through a pair of N—H⋯N hydrogen bonds involving one -NH(2) group H atom and second pair of N—H⋯N hydrogen bonds involving the other -NH(2) 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⋯π inter­actions, resulting in a three-dimensional network. The crystal studied was a non-merohedral twin with refined components 0.906 (1):0.094 (1).
