Supramolecular hydrogen-bonded hexamers in two 5-aryl-3-methyl-1-phenyl-1,6,7,8-tetrahydropyrazolo[3,4-b][1,4]diazepines.
In both title compounds, i.e. 3-methyl-1,5-diphenyl-1,6,7,8-tetrahydropyrazolo[3,4-b][1,4]diazepine, C(19)H(18)N(4), (I), and 5-(4-chlorophenyl)-3-methyl-1-phenyl-1,6,7,8-tetrahydropyrazolo[3,4-b][1,4]diazepine, C(19)H(17)ClN(4), (II), an N-H...N hydrogen bond links six molecules to form an R(6)(6)(30) ring. Compound (I) crystallizes in the R3 space group and (II) crystallizes in P1 with three molecules in the asymmetric unit. The molecule of (I) contains a disordered seven-membered ring.
