abstract

  • The crystal structures of propionaldehyde complex (RS,SR)-(5-C5H5)Re(NO)(PPh3)(2-OCHCH2CH3)]+ PF6- (1b+ PF6s-; monoclinic, P21/c (No. 14), a = 10.166 (1) , b = 18.316(1) , c = 14.872(2) , = 100.51(1), Z = 4) and butyraldehyde complex (RS,SR)-[(5-C5H5)Re(NO)(PPh3)(2-OCHCH2CH2CH3)]+ PF6- (1c+PF6-; monoclinic, P21/a (No. 14), a = 14.851(1) , b = 18.623(3) , c = 10.026(2) , = 102.95(1), Z = 4) have been determined at 22C and -125C, respectively. These exhibit C{A figure is presented}O bond lengths (1.35(1), 1.338(5) ) that are intermediate between those of propionaldehyde (1.209(4) ) and 1-propanol (1.41 ). Other geometric features are analyzed. Reaction of [(5-C5H5)Re(NO)(PPh3)(ClCH2Cl)]+ BF4- and pivalaldehyde gives [(5-C5H5)Re(NO)(PPh3)(2-OCHC(CH3)3)]+BF4- (81%), the spectroscopic properties of which establish a C{A figure is presented}O binding mode. 1993.
