Potassium pentaborate
The title compound, K[B(5)O(7)(OH)(2)], was obtained from a hydrothermal reaction. The structure is composed of one K(+) cation and a polyborate (1) (∞)[B(5)O(7)(OH)(2)](−) anion, which consists of two six-membered rings linked by a common BO(4) tetrahedron. The [B(5)O(7)(OH)(2)](−) units are link...

| Sumario: | The title compound, K[B(5)O(7)(OH)(2)], was obtained from a hydrothermal reaction. The structure is composed of one K(+) cation and a polyborate (1) (∞)[B(5)O(7)(OH)(2)](−) anion, which consists of two six-membered rings linked by a common BO(4) tetrahedron. The [B(5)O(7)(OH)(2)](−) units are linked together through two exocyclic O atoms to neighbouring units, forming a helical chain structure extending parallel to [010]. Adjacent chains are further connected into a three-dimensional structure by K—O bonds and weak O—H⋯O hydrogen-bond interactions. |
