Crystal structure of cis-anti-cis-di­cyclo­hexane-18-crown-6 aceto­nitrile disolvate

The title compound (systematic name: cis-anti-cis-2,5,8,15,18,21-hexa-oxatri-cyclo-[20.4.0.0(9,14)]hexa-cosane aceto-nitrile disolvate), C20H36O6·2CH3CN, crystallizes from an aceto-nitrile solution of di-cyclo-hexane-18-crown-6 on evaporation. The mol-ecule is arranged around a center of symmetry with half the crown ether mol-ecule and one mol-ecule of aceto-nitrile symmetry independent. All O-...

cis-cis-trans-Bis(acetonitrile-κN)dichloridobis(triphenyl­phosphine-κP)ruthenium(II) acetonitrile disolvate

The title compound, [RuCl(2)(C(2)H(3)N)(2)(C(18)H(15)P)(2)]·2C(2)H(3)N, was obtained upon stirring an acetonitrile/ethanol solution of [RuCl(2)(PPh(3))(3)]. In the crystal structure, each Ru(II) ion is coordinated by two Cl [Ru-Cl = 2.4308 (7) and 2.4139 (7) Å], two N [Ru-N = 2.016 (2) and 2.003 (2) Å], and two P [Ru-P = 2.3688 (7) and 2.3887 (7) Å] atoms in a distorted octa-hedral geometry.

Crystal structure of cis-tetra­aqua­dichlorido­cobalt(II) sulfolane disolvate

In the title compound, [CoCl2(H2O)4]·2C4H8SO2, the Co(II) cation is located on the twofold rotation axis and is coordinated by four water mol-ecules and two adjacent chloride ligands in a slightly distorted octa-hedral coordination environment. The cisoid angles are in the range 83.27 (5)-99.66 (2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packin...

Dibenzo-18-crown-6

The asymmetric unit of the title compound, C(20)H(24)O(6), contains two mol-ecules that are identical within standard deviations concerning bond lengths and angles as well as their conformations. In the crystal structure, weak C-H⋯O inter-actions help to consolidate the packing.

Crystal structure of (18-crown-6)potassium(I) [(1,2,3,4,5-η)-cyclo­hepta­dien­yl][(1,2,3-η)-cyclo­hepta­trien­yl]cobalt(I)

The reaction of bis-(anthracene)cobaltate(-I) with excess cyclo-hepta-triene, C7H8, resulted in a new 18-electron cobaltate containing two different seven-membered ring ligands, based on single-crystal X-ray diffraction. The asymmetric unit of this structure contains two independent cation-anion pairs of the title complex, [K(18-crown-6)][Co(η(3)-C7H7)(η(5)-C7H9)], where 18-crown-6 stands for 1...
