A brilliant purple octahedral single crystal is hydrothermally synthesized by the reaction of CoCl2·6H2O, H3BO3 and H3PO4 in NaOH aqueous solution of CH3(CH2)15N(CH3)3Br, and its crystal structure has been characterized by single-crystal X-ray diffraction. The compound, NaCo(H2O)2BP2O8·H2O (Mr = 336.72), belongs to hexagonal, space group P6122 with a = 9.447(5), c = 15.83(1) (A。), V = 1223(1) (A。)3, Dc = 2.742 g/cm3, Z = 6, F(000) = 1002 and β= 2.606 mm－1. The three-dimensional framework in the compound is built up from the linkage tetrahedral ribbons, in which the BO4 and PO4 tetrahedra alternate with CoO6 octahedra. The sodium ions and water molecules are located within the free thread of the helical ribbons.
