abstract

  • The styrene complex [(5-C5H5)Re(NO)(PPh3(H2C = CHC6H5)]+BF4-1 (1) can exist as two configurational diastereomers, RS,SR and RR,SS, that differ in the C = C enantioface bound to rhenium. Crystal structures show that the eleven atom (5-C5H5)Re(NO)-(P)(C-C) units of each are virtually superimposable ((RS,SR)-1; triclinic, P1, a = 11.438(2) A , b = 12.449(3) A , c = 10.712(2) A , = 99.86 (1), = 105.01(1), = 99.43(1), Z = 2; (RR,SS)-1; monoclinic, P21/n (No. 14), a = 9.673(1) A , b = 9.517(1) A , c = 30.928(2) A ,, = 94.98(1), Z = 4). Steric interactions between the styrene phenyl group and cyclopentadienyl ligand in the less stable diastereomer (RR,SS)-1 are apparent. These and other structural features are analyzeed in detail. 1995.
