The triclinic form of dipotassium cobalt(II) bis­(dihydrogendiphosphate) dihydrate

In the title compound, K(2)Co(H(2)P(2)O(7))(2)·2H(2)O, the octa­hedrally coordinated Co(2+) ion lies on an inversion centre. Two bidentate dihydrogendiphosphate anions form the equatorial plane of the [CoO(6)] octa­hedron which is completed by two water mol­ecules in axial positions. This results in...

description In the title compound, K(2)Co(H(2)P(2)O(7))(2)·2H(2)O, the octa­hedrally coordinated Co(2+) ion lies on an inversion centre. Two bidentate dihydrogendiphosphate anions form the equatorial plane of the [CoO(6)] octa­hedron which is completed by two water mol­ecules in axial positions. This results in isolated {Co(H(2)O)(2)[H(2)P(2)O(7)](2)}(4−) entities linked into a three-dimensional network through K—O bonds and O—H⋯O hydrogen-bonding inter­actions involving the dihydrogendiphosphate anions and water mol­ecules. The dihydrogendiphosphate anion, (H(2)P(2)O(7))(2−), is bent and shows an almost eclipsed conformation.
