Single crystals of the strontium phosphate orthoborate metaborate, Sr{sub 10}[(PO{sub 4}){sub 5.5}(BO{sub 4}){sub 0.5}](BO{sub 2}), were grown from the melt and investigated by X-ray diffraction (space group P3-bar, No. 147; a=9.7973(8) A, c=7.3056(8) A, V=607.29(10) A{sup 3}, Z=1). The crystal structure is closely related to apatite and contains linear metaborate groups, [BO{sub 2}]{sup -} (point group D{sub i}nfinity{sub h}, B-O=1.284(11) A) taking positions within the channels running along the three-fold inversion axis. Strontium sites are found to be fully occupied while [PO{sub 4}]{sup 3-} tetrahedra are partially replaced by [BO{sub 4}]{sup 5-} groups. - Graphical abstract: Single crystals of the strontium phosphate orthoborate metaborate, Sr{sub 10}[(PO{sub 4}){sub 5.5}(BO{sub 4}){sub 0.5}](BO{sub 2}), were grown from the melt and structurally characterized. The crystal structure is closely related to apatite and contains uncommon linear [BO{sub 2}]{sup -} metaborate groups taking positions within the channels running along the three-fold inversion axis.
