摘要：
The crystal structures of two 12-membered crown ethers, benzo-12-crown-4 (1) and naphtho-12-crown-4 (2), have been determined by X-ray analysis. Both structures are molecular. Compound 1 is monoclinic, P2(1)/b, a = 8.466(3), b = 8.019(3), c = 33.590(10) angstrom, gamma = 90.99(3)-degrees. The unit cell contains two crystallographically independent molecules of 1 with similar conformations. Compound 2 is also monoclinic, P2(1)/a, a = 24.148(8), b = 14.535(4), c = 7.987(5) angstrom, gamma = 102.87(2)-degrees. Two independent molecules in the unit cell have significantly different conformations.
