Pentaborate polyanion in the crystal structure of ulexite, NaCaB5O6(OH)6*5H2O
January 1, 1964
Triclinic ulexite crystals contain isolated borate polyanions [B5O6(OH)6]3- related to the well known pentaborate polyanion [B5O6(OH)4]- by addition of two hydroxyl groups to two opposite B-O triangles. The isolated ulexite polyanions form the [B5O7(OH)4]n3n- chains previously found in crystals of the related mineral probertite, NaCaB5O7(OH)4·3H2O.
