A pi-stacked chain of hydrogen-bonded dimers in 3-tert-butyl-1-(4-chlorophenyl)-4-phenylindeno[1,2-b]pyrazolo[4,3-e]pyri din-5(1H)-one and a pi-stacked sheet of hydrogen-bonded chains in 3-tert-butyl-1-(4-chlorophenyl)-4-(4-methoxyphenyl)indeno[1,2-b]pyrazolo [4,3-e]pyridin-5(1H)-one

In 3-tert-butyl-1-(4-chlorophenyl)-4-phenylindeno[1,2-b]pyrazolo[4,3-e] pyridin-5(1H)-one, C(29)H(22)ClN(3)O, (I), inversion-related pairs of molecules are linked by C-H center dot center dot center dot O hydrogen bonds to form R(2)(2)(18) dimers, which are themselves linked into a chain by a pi-pi stacking interaction between inversion-related pairs of molecules. In 3-tert-butyl-1-(4-chlorophenyl)4-(4-methoxyphenyl) indeno[1,2-b] pyrazolo[4,3-e] pyridin-5(1H)one, C(30)H(24)ClN(3)O(2), (II), which crystallizes in the space group P (1) over bar, with Z' = 2 and with different orientations for the methoxy groups in the two independent molecules, a combination of C-H center dot center dot center dot O and C-H center dot center dot center dot pi (arene) hydrogen bonds links the molecules into chains of rings, which are further linked into sheets by a pi-pi stacking interaction.
