Hexaazide octahedral molybdenum cluster complexes: Synthesis, properties and the evidence of hydrolysis

This article reports the synthesis, crystal structure of new molybdenum hexaazide cluster complex ((Bu4N)-Bu-n)(2)H[{MO6I8})(N-3)(6)] (3) and comparison of its photophysical and electrochemical properties to those of earlier reported analogues ((Bu4N)-Bu-n)(2)I[{MO6X8}(N-3)(6)] (X = Cl, Br). Additionally, the dimerisation of 3 as a result of hydrolysis was revealed by mass spectrometry and single crystal X-Ray diffraction. Indeed, the structurally characterised compound ((Bu4N)-Bu-n)(4)[({MO6I8)(N-3)(5))(2)O] represents the first example of oxobridged dimer of octahedral molybdenum clusters complexes.
