Synthesis and structure of [Mo2O4(acac)2thala]·3C2H5OH with thala=3-(2-thienyl)-dl-alanine as a third bridging ligand between two molybdenum atoms

As part of our study on oxomolybdenum(V) complexes we present here the synthesis and crystal structure of a novel dimeric oxomolybdate(V) [Mo2O4(acac)2thala]·3C2H5OH (acac=acetylacetonato, thala=3-(2-thienyl)-dl-alanine) in which two molybdenum atoms are being bridged not only by two oxo-oxygens but additionally by the amino acid carboxylate group. Two octahedrally coordinated molybdenum atoms are singly bonded to each other at a distance of 2.5631(5) Å.
