inorganic compounds
The crystal structures of tetragonal [Co(H2O)6](H2PO2)2 and [Co0.5Ni0.05(H2O)6](H2PO2)2 have been determined. The crystals of hexaaquacobalt(II)/nickel(II) bis(hypophosphite) are a solid solution of CoII and NiIII hypophosphites. The packing of the Co(Ni) and P atoms is the same as in the structure of CaF2. The coordination number of six for metal is achieved by water molecules. The hypophosphite anion does not coordinate to the metal cation.

In a new polymorph of hexaaquamagnesium(II) bis(hypophosphite), [Mg(H2O)6](H2PO2)2, the planes of trans water molecules forming the octahedral coordination sphere of the Mg atoms are in a staggered conformation. The magnesium(II) cations are in a pseudo-face-centered cubic arrangement, with a 
10.294 Å and tetrahedral cavities are occupied by P atoms. Hypophosphite anions are hydrogen bonded to the coordinated water molecules.

In the title compound, the NiII cations have a pseudo-face-centered cubic cell, with cell parameter a 
10.216 Å and tetrahedral cavities occupied by P atoms. The NiII cation has an octahedral coordination sphere consisting of six water O atoms. The planes of oppositely coordinated water molecules are in a cross conformation. The geometry of the hypophosphite anion is close to point symmetry mm2. The hypophosphite anions are hydrogen bonded to the coordinated water molecules.

The Sr(H2PO2)2, Pb(H2PO2)2 and Ba(H2PO2)2 structures consist of layers of cations bridged by hypophosphite anions. The cations exhibit square antiprismatic coordination by O atoms.
inorganic compounds
The crystal structures of monoclinic α-, orthorhombic β- and orthorhombic γ-Cu(H2PO2)2 have been determined at different temperatures. Despite having different space groups, the structures of the α- and β-polymorphs are very similar. The structures of the polymeric layers in the γ-polymorph are quite different.
inorganic compounds
The LiH2PO2 and Be(H2PO2)2 structures consist of layers of cations bridged by hypophosphite anions. The cations are tetrahedrally coordinated by oxygen.

The structure of monoclinic (C2/c) cadmium bis[dihydrogenphosphate(I)], [Cd(H2PO2)2], consists of layers located at x = 0 and 
. The Cd cation has a distorted octahedral coordination and dihydrogenphosphate(I) anions act as tridentate bridging ligands. The Cd atoms are on sites of twofold symmetry, while all other atoms are in general positions. The compound is isotypic with Ca(H2PO2)2 [Goedkoop & Loopstra (1959). Ned. Tijdschr. Natuurkd. 25, 29-41].

inorganic compounds
The structures of the title compounds consist of layers of alkali cations and H2PO2- hypophosphite anions, with the latter bridging four cations within the same layer. The hypophosphite anion has a distorted tetrahedral arrangement, with the P atom at the centre and two O and two H atoms at the vertices.
