Linear trichromium complexes with direct Cr to Cr contacts. 1. Compounds with Cr3(dipyridylamide)4(2+) cores. Academic Article

abstract

• The preparation and structures of seven compounds that contain the Cr3(dpa)4(2+) core (dpa = the anion di(2-pyridyl)amide) are reported. The magnetic properties of several have been measured. In each case there are anionic ligands at each end of the Cr3(6+) chain, sometimes identical (2Cl-, 2CCPh-), sometimes different (Cl-, BF4-; Cl-, PF6-). Several of these compounds have a symmetrical arrangement of the three Cr atoms, with the two Cr-Cr distances equal at ca. 2.36 A, while others have an unsymmetrical arrangement. In the most extreme case the two Cr-Cr distances are 2.00 and 2.64 A. The electronic structures and the remarkable flexibility of the Cr3 arrangement are discussed.
