摘要: Abstract A set of bimetallic Co–Mo complexes has been synthesised in yields approximately 95% by the sequential dissolution ethylenediamine, different Co2+ carboxylates and ammonium heptamolybdate water. Data collected from elemental analysis, XRD, UV–Vis, IR, Raman, XPS, EXAFS spectroscopy suggest that all have similar structures correspond to general formula NH4(enH2)x[Co(en)3][Mo2O7L]·H2O, where L is oxalic, tartaric, citric or nitrilotriacetic acid residue. special feature presence two molybdenum atoms linked together an oxygen bridge octahedral tetrahedral environment, as well a cobalt 2+ atom environment with nitrogen ethylenediamine.
