摘要：
The X-ray crystal structures of two closely related Ag(I) complexes of 15-crown-5 and benza-15-crown-5 are reported. In the case of [Ag(15-crown-5)(2)] [SbF6] 1, pointing one of its oxygen atoms away from the Ag+ cation enables one of the crown ligands to take part in an intermolecular C-H ... O hydrogen bond. The analogous benzo-15-crown-5 species, [Ag(benzo-15-crown-5)(2)][SbF6] 2, is too rigid to attain the necessary conformation. Crystal data for I: P2(1)/c, a=8.4481(3), b=25.5813(9), c=13.2773(4)Angstrom, beta = 101.354(2)degrees. Z=4, unique data: 5187 R-1 [F-2>2 sigma(F-2)] 0.0259. Compound 2: P (1) over bar, a=8.6511 (15)Angstrom, b=10.2322(18)Angstrom, c=19.291(3)Angstrom alpha=103.704 (2)degrees, beta = 101.274(2)degrees, gamma = 95.952(2)degrees, Z=2, unique data: 5803R(1) [F-2>2 sigma(F-2)] 0.0931.
