The triazacyclohexane ring adopts a twist-boat conformation with torsi
on angles -25.3 (2), -41.3 (2), 70.3 (2), -27.7 (2), -35.8 (2) and 66.
0 (2)degrees. The N-C(aryl) bonds from the ring have lengths of 1.356
(3), 1.382 (3) and 1.400 (3) angstrom and are inclined at 3.3 (2), 21.
2 (2) and 29.5 (3)degrees to the CH2-N-CH2 planes. The N-C bond length
s in the triazacyclohexane ring are 1.442 (3)-1.474 (3) angstrom. The
pyridine molecules are accommodated in an ordered manner in channels a
ligned along the screw axes parallel to b.
