Bottom Line: The crystal structure of the title compound, [Mg(H2P2O6)(H2O)4] n , is built up from (H2P2O6)(2-) anions bridging Mg(2+) cations into chains extending parallel to [011].The centrosymmetric (H2P2O6)(2-) anion has a staggered conformation whereby the tetra-valent phospho-rus atom is surrounded tetra-hedrally by three O atoms and by one symmetry-related P atom.A three-dimensional O-H⋯O hydrogen-bonded network of medium strength involving the P-OH group of the anion and the water mol-ecules is present.

ABSTRACT
The crystal structure of the title compound, [Mg(H2P2O6)(H2O)4] n , is built up from (H2P2O6)(2-) anions bridging Mg(2+) cations into chains extending parallel to [011]. The Mg(2+) ion is located on an inversion centre and is octa-hedrally coordinated by the O atoms of two (H2P2O6)(2-) anions and four water mol-ecules. The centrosymmetric (H2P2O6)(2-) anion has a staggered conformation whereby the tetra-valent phospho-rus atom is surrounded tetra-hedrally by three O atoms and by one symmetry-related P atom. A three-dimensional O-H⋯O hydrogen-bonded network of medium strength involving the P-OH group of the anion and the water mol-ecules is present.

Mentions: The crystal structure of [Mg(H2P2O6)(H2O)4] exhibits a three-dimensional hydrogen-bonded network, in which the (H2P2O6)2– anions are joined into ribbons along [100] by centrosymmetric pairs of PO3—H3⋯O2 hydrogen bonds (Table 1 ▸ and Fig. 3 ▸). The O⋯O distances between the (H2P2O6)2– anions and water mol­ecules located between the ribbons range from 2.786 (3) to 2.829 (3) Å), indicating hydrogen bonds of medium strength (Table 1 ▸). These values agree very well with those reported for Rb2H2P2O6·2H2O (Wu et al., 2012 ▸).
