[VCl2(15-crown-5)]+[VOCl4]- has been prepared by the reaction of VCl4 with 15-crown-5 in acetonitrile solution in the presence of water, forming black-brown single crystals. They were characterized by IR spectroscopy as well as by an X-ray structure determination. Space group Pnma, Z = 4, 1530 observed unique reflexions, R = 0.052. Lattice dimensions at -120°C: a = 1128.5(4), b = 1063.3(3), c = 1680(1) pm. The compound forms ions, in which the cation contains vanadium(+III), which is seven coordinate by the five oxygen atoms of the crown ether molecule and by two chlorine atoms in axial positions of a pentagonal bipyramide. The [VOCl4]- anion contains vanadium (+V) with approximately tetragonal symmetry

[Na(15-crown-5)]2S6 was obtained from Na2S4 und 15-crown-5 in acetonitrile. Its crystal structure was determined by X-ray diffraction with 2968 observed reflexions, R = 0.119. Crystal data: a = 861.4(9), b = 1006(1), c = 2097(1) pm, α = 89.7(1), β = 100.20(8), γ = 114.6(1)°, Ζ = 2, space group Ρ 1̄. The chain-like S62- ion has transoid conformations, each of its terminal atoms is in contact with one Na+ ion which in turn is coordinated with one crown ether molecule.

Abstract The caesium hydrogen benzoylcyanoximate (L-) complex with 18-crown-6 of composition Cs(18-crown-6){H(L)2} has been prepared and studied by means of X-ray diffraction [monoclinic, space group P21/n, with a = 9.906(1), b = 18.387(3), c = 18.855(3)Å, β = 90.13(1)°, V = 3434.3(9) Å, Z = 4; final R1 = 0.043 for the 6431 independent reflections used. The lattice consists of Cs(18-crown-6)+ cations and complex hydrogen oximate anions {H(L)2}-, formed via strong hydrogen bonding between the oxygen atoms of nitroso-groups [O - - - O ca. 2.456(5)Å]. The caesium atom deviates by 1.492(3) Å from the mean plane of the oxygen atoms of the macrocyclic ether (dominant orientation of disordered ligand, 60%) and adopts a typical “sunrise coordination” [Cs-O (ether) 3.040(9)-3.312(7) Å]. The hydrogen oximate groups are bonded to the metal center only on one side of the crown ether plane via the oxygen atoms of nitroso-groups and the nitrogen atoms of cyano groups (Cs-O ca. 3.040(9), 3.312(7) Å; Cs-N ca. 3.469(5), 3.679(6) Å). The coordination polyhedron of Cs+ can be described as a distorted bicapped tetragonal prism.
