Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The title salts calcium (glycinato‐κ²<italic>N</italic>, <italic>O</italic>)oxidobis(peroxido‐κ²<italic>O</italic>, <italic>O</italic>′)vanadate(V) tetrahydrate, Ca[VO(O₂)₂(NH₂CH₂COO)]·4H₂O, and strontium (glycinato‐κ²<italic>N</italic>, <italic>O</italic>)oxidobis(peroxido‐κ²<italic>O</italic>, <italic>O</italic>′)vanadate(V) tetrahydrate, Sr[VO(O₂)₂(NH₂CH₂COO)]·4H₂O, crystallized at pH <italic>ca</italic> 7.4 with similar lattice parameters. The glycinate anion acts as a bidentate <italic>N</italic>, <italic>O</italic>‐chelating ligand, and the V atom has a pentagonal bipyramidal geometry, with two η²‐peroxo groups and the glycinate N atom in the equatorial plane, and one terminal oxo and a glycinate O atom at the axial positions. The H atoms of three of the four water molecules in the strontium salt exhibited disorder over three positions for each molecule.</p> </abstract>
