The title salt, [K(C18H36N2O6)][Co(CO)4], is an example of a classical carbonyl­metalate. The asymmetric unit contains one cation and one tetrahedral anion, both in general positions. Based on comparison of the four carbonyl C—O bond lengths and C—Co—C angles, the anion is unperturbed by the cation, which is normal for an alkali metal fully encased by a cryptand cage.

Comment top

The title salt (Fig. 1) contains the classical metal carbonyl anion (Ellis, 2003) tetracarbonylcobaltate, which has now appeared in the Cambridge Structural Database (CSD, Version 5.35, update No. 2, Febuary 2014, Allen, 2002) 86 times, 70 for which it serves simply as an anion of modest bulk, as in the title salt. In eleven instances it is part of an alkali metal or thallium network, and in the remaining five occurrences it is coordinated through an oxygen atom to a transition metal or lanthanide.

Because the cobaltate is an unperturbed anion in this salt, the IR stretch is very strong and without features, as expected for a tetrahedron. In contrast, the very strong IR stretch of K[Co(CO)4] in instances in which there can be monodentate or tridentate K···O interactions has a shoulder that is due to symmetry reduction from Td to C3v (Edgell & Lyford, 1971).

Experimental top

Argon was removed under vacuum from a deep pinkish-red solution of [K([2.2.2]cryptand)][Co(η4-C14H10)2]·0.5THF (Brennessel et al., 2002) stirring in tetrahydrofuran (THF) at room temperature. Carbon monoxide (1 atm) was added, and the solution became immediately colorless. After a few minutes, the carbon monoxide and most of the solvent were removed under vacuum. Argon was reintroduced and diethyl ether was added to extract the anthracene and to precipitate the product. After filtering, washing (diethyl ether), and drying, the colorless salt was obtained in quantitative yield.

IR (νCO, THF, cm-1): 1892 vs; IR (νCO, Nujol mull, cm-1): 1878 vs br; 59Co NMR (71.15 MHz, CD3CN, 293 K, external reference 0.1 M K3[Co(CN)6] in D2O at 0.0 p.p.m., δ, p.p.m.): -3015.7 (s). Colorless blocks were grown from a pentane-layered THF solution at 273 K.

Refinement top

All H atoms were placed geometrically and treated as riding atoms: C—H = 0.99 Å with Uiso(H) = 1.2Ueq(C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
