Bisμ-NN′-bis(26-diisopropylphenyl)ethene-12-diamido-14(η2);1:2κ4 N:N;3:4κ4 N:N-bis(diethyl ether)-1κO4κO-di-μ-hydrido-2:3κ4 H:H-23-dichromium(II)-14-dilithium(I) pentane hemisolvate

摘要

The title compound, [Cr2Li2(C26H36N2)2(μ-H)2(C4H10O)2]·0.5C5H12, 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-diisopropyl­phen­yl)ethene-1,2-diamido ligand via its two N atoms. Additionally, two diametrically opposed lithium ether adducts coordinate in an η⁴ mode on the backbone of the ligands. There is a crystallographic inversion center in the middle of the Cr2H2 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.
