Abstract

The Cp)2Ni2Fe(CO)3(μ3-C2H2) and Cp)2Ni2Fe(CO)3(μ3-C2H2) (B) complexes have been synthesized and spectroscopically characterized. An accurate X-ray study and a comparison with related structures shows that the substituents of the alkyne ligands exert considerable effects on the bonding parameters. Crystal data for complex A, monoclinic space group P21/n, a = 8.418(1), b = 15.779(2), c = 14,493(1) Å, β = 91.64(1)°, Z = 4, 2753 observed reflections, R = 0.022; crystal data for complex B, monoclinic space group C2/c, a = 16.2189(7), b = 7.445(3), c = 25.745(5) Å, β = 103.74(3), Z=8, 1853 observed reflections, R = 0.051. © 1994 Plenum Publishing Corporation.
