Notes:
The complexes [9,10-dihydroanthracene][tricarbonylchromium]n [9,10-DHA][Cr(CO)3]n [n = 1 (1), 2 (2)] and the related mono- and bis(tricarbonylchromium) complexes of 2,6- and 2,7-di-tert-butyl-9,10-dihydroanthrancene [2,6-DB-9,10-DHA][Cr(CO)3]n [n = 1 (3), 2 (4)] and [2,7-DB-9,10-DHA][Cr(CO)3]n [n = 1 (5), 2 (6)] have been prepared by heating the 9,10-DHA species in the presence of hexacarbonylchromium [Cr(CO)6]. Evidence for the existence of the complex [2,6,9-tri-tert-butyl-9,10-DHA][Cr(CO)3] (7) is also presented. The complexes have been characterised spectroscopically, and for complex 1 an X-ray crystallographic structure determination has been carried out. This complex adopts the unexpected structure in which the non-coordinated arene ring is bent towards the Cr(CO)3 moiety. The syntheses and spectroscopic characterisations of 2,6- and 2,7-di-tert-butylanthracene (2,6- and 2,7-DBA), 2,6- and 2,7-di-tert-butyl-9,10-dihydroanthracene (2,6-and 2,7-DB-9,10-DHA), 2,6,9-, 2,7,9-, and 2,7,10-tri-tert-butyl-9,10-dihydroanthracene (2,6,9-, 2,7,9- and 2,7,10-TB-9,10-DHA), and 2,6,9,10- and 2,7,9,10-tetra-tert-butyl-9,10-dihydroanthracene(2,6,9,10- and 2,7,9,10-TeB-9,10-DHA) are also given.
