Abstract The crystal structure of trispotassium [cis-trioxo(nitrilotriacetato)molybdate (VI)] monohydrate, C6H8K3MoNO10, has been determined. The crystals are monoclinic, space groupP21/c,a = 9.700(4),b = 19.628(6),c = 7.608(2) Å, β = 110.58(4) ° andZ = 4. X-ray data were collected by counter methods using MoKα. radiation, and least-squares refinement led toR = 0.055 for the 2234 independent reflections for which ¦F 0¦2 〉 σ(¦F 0¦2). The anion contains acis-trioxo metal system, while the ligand coordinates as a tridentate through its nitrogen atom and two of the three carboxylate oxygen atoms, the Mo atom being in a distorted octahedral environment. The two glycinato rings involved in the coordination are mutuallycis. The mean Mo-O (terminal) bond length is 1.74 Å and the lengths of the metal-ligand bonds are Mo-O 2.18, 2,25 Å; Mo-N 2.39 Å.
