Syntheses and Crystal Structure of the Crown Ether Complexes (18-Crown-6)*2CH3CN, *CH3CN, and PF6

Single crystals of (18-crown-6)*2CH3CN were obtained by cooling a solution of 18-crown-6 in acetonitrile to 4 deg C.Space group P21/n, Z = 2.629 observed independent reflexions, R = 0.062.Lattice dimension at 19 deg C: a = 911.7(1), b = 852.0(1), c = 1370.0(2) pm; beta = 104.61(1) deg.The compound forms a molecular structure with approximate D3d symmetry of the crown ether molecule, and C-H…O interactions of the acetonitrile molecules with the crown ether, the H…O distances being 243, 253, and 267 pm respectively. *CH3CN is formed as a by-product of the reaction of ReNCl4 with sodium fluoride in acetonitrile in the presence of 15-crown-5 and traces of water.Space group P<*>, Z = 2, 3107 observed independent reflexions, R = 0.045.Lattice dimensions at 19 deg C: a = 823.4(1), b = 107.8(1), c = 1204.0(1) pm; alpha = 112.40(1) deg, beta = 94.35(1) deg, gamma = 104.63(1) deg.The compound forms ion pairs, in which the sodium atom is sixfold coordinated by the five oxygen atoms of the crown ether molecule, as well as by one oxygen atom of the ReO4(-) ion, which is only slightly distorted.The bond length Na-OReO3 is 237.8(8) pm, the bond angle NaORe is 164.3(5) deg. PF6 is formed in the reaction of Related Products of 33100-27-5
