Crystal structure of 2-(2,6-diisopropyl-phenylamino)-6-(2,4,6-triisopropylphenyl)- pyridinium [2-(2,6-diisopropyl-phenylamido)-6-(2,4,6-triisopropylphenyl)- pyridinium]-( μ-chloro)-di( μ-oxo)-tetrachloro-tetrahydrofuran-dichromate( IV) pentane solvate, (C32H45N2)[(C32H44N2)Cl5Cr2O2(C4H8O)]·C5H12

Abstract

Source of materialCrCl 3 (thf) 3 (0.43 g, 1.15 mmol), KAp* (0.57 g, 1.15 mmol) (Ap* = deprotonated (2,6-diisopropyl-phenyl)-[6-(2,4,6-triisopropylphenyl)-pyridin-2-yl]-amine) [1] and THF(30 mL)were stirred for 16 hinaSchlenk flask. The solventwasremoved under vacuum and amixture of n -pentane/ether (60 mL;1:1, v / v )wasadded. The suspension wasfiltered and upon standing at-80°Cfor five days, green crystals of the title complex were formed. Experimental detailsThe Hatoms attached to Natoms were included in the refinement process due to their importance with regard to the H-bond pattern. DiscussionThe title compound is adinuclearc hromium(IV)c omplex. Each of the chromium atoms adopts anoctahedralcoordination. They are coordinated by two chloro ligands and connected via a m -chloro and two m -oxygen bridges with bond angles of
