Abstract

Abstract  

Addition of CrI2 to the lithium salt of N-N′-bis(2,6-diisopropylphenyl)-2,4-diketiminate in diethylether yields a Cr(II) iodide complex with a coordinated, solvated LiI salt. This complex is the intermediate in the synthesis of a bridging iodide complex that is itself a precursor to a side-on bridging dinitrogen complex. This complex crystallizes in the P21/n space group with the crystal cell parameters a = 12.3160(19) Å, b = 21.067(3) Å, c = 15.837(3)Å, β = 96.767°, V = 4080.6(11) Å3 and Z = 4.
