X-ray Structural Characterization of Molybdate-tripeptide Complex, [Mo4O12(glycylglycylglycine)2]·9H2O

The first isolated polyoxomolybdate-tripeptide complex, [Mo4O12(glycylglycylglycine)2], is an infinite centrosymmetric complex of the Mo4O12 unit in which a pair of Mo atoms is singly bridged by a glycylglycylglycine carboxylate group as a bidentate ligand resulted in four edge-shared MoO6 octahedral linkage. [Mo4O12]n exhibits a corrugated sheet-belt structure of four co-planar Mo atoms linked by four triply-bridging O atoms with cis-configurated two terminal O atoms for each Mo atom.
