The title molecule, C 10H 16N20 (I), has approximate mirror symmetry with the main chain fully extended. The main torsion angles defining the molecular conformation are O--Cw3--Cw3--Cw 58.9 (4) and -60.5 (4) °. The mean principal dimensions include N~Csp 1.13 (1), Csp--Cw3 1.46 (1) and Csp3--O 1.410 (6) A. The two nitrile groups are oriented cis to one another [N=Csp... Csp:--N 4.4o(5) °] and the intramolecular N.-.N separation is 4.70 (1) A. t Present address: Abstract Infinite polar chains of
