Popis:	C 15H2aNOs. C4H12 N+ . C10 2, orthorhombic, Pna2t, a -- 12.309 (2), b = 20.821 (3), c = 9.237 (1) /~, U = 2367.2 (6)/k a, Z = 4, D x = 1.321 Mg m -3. Least-squares refinement for 2568 reflections (measured at 113 K) gave a final discrepancy index R(F) = 0.038. The crown-ether tert-butylammonium cation complex has approximate m symmetry; the tert- BuNH + forms hydrogen bonds to two O atoms and the pyridine N atom in the macrocyclic ring.
