Potassium sodium copper(II) diphosphate(V), KNaCuP2O7, was synthesized by solid-state reactions. It crystallizes in the α-Na2CuP2O7 structure type in space group P21/n. In the crystal, CuO5 square-pyramids are linked to nearly eclipsed P2O7 groups by sharing corners to build up corrugated layers with composition [CuP2O7]2− that extend parallel to (010). The K+ and Na+ cations reside in the interlayer space and are connected to nine and seven O atoms, respectively. The structural model was validated by bond-valence-sum (BVS) and charge-distribution (CHARDI) analysis.

Exchange Technique

The title compound, KNa[CoIII(OH)7{Mo6O17}]·8H2O, was obtained by the ion-exchange technique from K3[Co(μ3-OH)6Mo6O18]·7H2O. Six μ3-O atoms and one O atom of the bridging μ2-O atom are protonated. This novel polyanion protonated by an extra H atom is an unexpected polyanion species among theB-series Anderson-type polyoxidometalates (POMs), [Xn+(μ3-OH)6Mo6O18](6–n)–] (X= heteroatom). The extra H atom (seventh H atom) in the polyanion does not lie on a crystallographic centre of symmetry, but is located at the mid-point between two μ2-O atoms of adjacent polyanions, and forms a very short hydrogen bond [2.430 (5) Å]. The present structure is considered as particularly significant in understanding noncentrosymmetric strong hydrogen bonding.
