Comment top

The title compound, 3,5-dimethyl-1,4,7-triphenyl-1H,7H-pyrazolo[3,4 − b:4',3'-e]pyridine, (I), is isomorphous with 3,5-dimethyl-1,7-diphenyl-4-(2-pyridinyl)-1H,7H-pyrazolo[3,4 − b:4',3'-e]pyridine, (II) (Low et al., 2003), the only difference being that in (I) a phenyl ring replaces the pyridyl ring of (II).

The bonds and angles for this compound are identical to (II) within 3σ, with the exception of those listed in Table 1.

Experimental top

A mixture of 5-amino-3-methyl-1-phenylpyrazole (10 mmol) and benzaldehyde (20 mmol) was placed into Pyrex-glass open vessels and irradiated in a domestic microwave oven for 1 min (at 600 W). The solid was filtered, washed with ethanol, dried and recrystalized from ethanol. Yield 65%, m.p. 516 K. Analysis calculated for C₂₆H₂₀N₆: C 74.98, H 4.84, N 20.18%; found: C 74.93, H 4.78, N 20.15%.

Special details top

Experimental. The program DENZO-SMN (Otwinowski & Minor, 1997) uses a scaling algorithm (Fox & Holmes, 1966) which effectively corrects for absorption effects. High redundancy data were used in the scaling program hence the 'multi-scan' code word was used. No transmission coefficients are available from the program (only scale factors for each frame). The scale factors in the experimental table are calculated from the 'size' command in the SHELXL97 input file.
