title: Bis[μ-N,N'-bis(2,6-diisopropylphenyl)ethene-1,2-diamido]-1,4(η);1:2κN:N;3:4κN:N-bis(diethyl ether)-1κO,4κO-di-μ-hydrido-2:3κH:H-2,3-dichromium(II)-1,4-dilithium(I) pentane hemisolvate.
abstract: The title compound, [Cr(2)Li(2)(C(26)H(36)N(2))(2)(μ-H)(2)(C(4)H(10)O)(2)]·0.5C(5)H(12), is a binuclear chromium complex bridged by two hydrogen atoms. Each chromium atom is coordinated in a distorted square-planar geometry by one chelating bis-(2,6-diisopropyl-phen-yl)ethene-1,2-diamido ligand via its two N atoms. Additionally, two diametrically opposed lithium ether adducts coordinate in an η(4) mode on the backbone of the ligands. There is a crystallographic inversion center in the middle of the Cr(2)H(2) ring. One of the isopropyl groups is disordered over two positions in a 0.567 (7):0.433 (7) ratio. Disorder is also observed in the pentane hemisolvate molecule.
