Abstract

The crystal structure of the title complex has been determined
from diffractometer X-ray intensity data by means of Patterson ·
and Fourier methods and refined by the full matrix least-squares
technique to an R index of 0.060 (Rw = 0.064). The crystals are
built up of pyH+ cations and [Mo20sCl4 (C2HsO) (HOC6H4C02)J2-
anions. Each molybdenum atom of the binuclear anion is octahedrally
coordinated, being bonded to two oxo-oxygen atoms, one
terminal (1.669 and 1.670 A) and one bridging (1.908 and 1.916 A),
one bridging ethoxo-oxygen atom (1.963 and 1.964 A), one salicylato-
oxygen atom (2.295 and 2.317 A) and two chlorine atoms
(from 2.399 to 2.432 A). The terminal oxo-oxygens occupy a cis-
position with respect to the Mo20 2 bridge. The dihedral angle
between the two Mo02 planes within the bridge amounts to 164.9°.
The Mo-Mo bond lengths is 2.646A.
