چکیده

The asymmetric unit of the title compound, [Mo(C(18)H(24)N(2))(3)][Mo(6)O(19)]·4CH(3)CN, comprises an [Mo(di-t-Bu-bipy)(3)](2+) cation (di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine), two halves of Lindqvist-type [Mo(6)O(19)](2-) anions (with each anion completed by the application of a center of inversion) and four acetonitrile solvent mol-ecules. The geometry around the metal atom of the cation resembles a distorted octa-hedron, with each of the three di-t-Bu-bipy ligands being almost planar [deviation from planarity < 6.3 (2)°]. Supra-molecular inter-actions, namely Mo=O⋯π, C N⋯π, C-H⋯O and C-H⋯N, along with electrostatic forces, mediate the crystal packing. Two of the tert-butyl groups are affected by rotational disorder which was modeled over two distinct positions with major site occupancies of 0.707 (9) and 0.769 (8).

In the title compound, [Co(C(10)H(8)N(2))(3)][Mo(6)O(19)], the Co(2+) cation is surrounded in a distorted octa-hedral coordination by six N atoms from three 2,2'-bipyridine ligands. The distribution of Mo-O bond lengths in the Lindqvist isopolyanion is consistent with other structures containing the same unit. In the crystal, the cations and anions are linked by C-H⋯O inter-actions.

The asymmetric unit of the title compound, [Co(2)(C(2)O(4))(C(10)H(8)N(2))(4)][W(6)O(19)], consists of one half of the complex [Co(2)(C(2)O(4))(C(10)H(8)N(2))(4)](2+) cation and one half of the Lindqvist-type [W(6)O(19)](2-) isopolyanion. Both constituents are completed by crystallographic inversion symmetry. In the dimeric cation, the Co(II) atom is surrounded in a distorted octa-hedral coordi...

μ-Oxido-bis­[chlorido(4,4′-di-tert-butyl-2,2′-bipyridine-κ2 N,N′)dioxido­molybdenum(VI)] 0.2-hydrate

The title hydrate, [Mo(2)Cl(2)O(5)(C(18)H(24)N(2))(2)]·0.2H(2)O, has been isolated as the oxidation product of [Mo(η(3)-C(3)H(5))Cl(CO)(2)(di-t-Bu-bipy)] (where di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine). A μ-oxide ligand bridges two similar MoCl(di-t-Bu-bipy)O(2) units, having the terminal oxide ligands mutually cis, and the chloride and μ-oxide trans to each other. In the binuclear c...

The title complex, [(C(4)H(9))(4)N](2)[Mo(6)(C(7)H(6)ClN)O(18)], was prepared by the reaction of (Bu(4)N)(4)[α-Mo(8)O(26)] and 2-methyl-5-chloro-aniline hydro-chloride with N,N'-dicyclo-hexyl-carbodiimide as dehydrating agent in dry acetonitrile solution. The aryl-imido ligand is linked to an Mo atom of the Lindqvist-type hexamolybdate anion by an Mo N triple bond, with a bond length of 1.732 (...

Bis(tetra­butyl­ammonium) [2-(eth­oxy­carbony)phenyl­imido]-μ6-oxido-dodeca-μ2-oxido-penta­oxidohexa­molybdenum diethyl ether hemisolvate

In the title complex, [(C(4)H(9))(4)N](2)[Mo(6)O(18)(C(9)H(9)NO(2))]·0.5C(4)H(10)O, the aryl-imido ligand is linked to an Mo atom of the Lindqvist-type polyoxidometalate anion by an Mo N bond of 1.726 (4) Å. The Mo N-C angles are 160.7 (5) and 167.6(5)° because of disorder affecting the aryl group, and is typical for the imido monodentate behaviour described in analogous hybrids. Light componen...
