摘要	A new compound alpha-SrGaBO4 has been synthesized by solid state reaction at high temperatures, and its structure has been solved by direct methods from powder X-ray diffraction. alpha-SrGaBO4 has an orthorhombic system, Pccn space group, with lattice parameters a = 15.3154(7) Angstrom, b = 8.9186(4) Angstrom, c = 5.8130(3) Angstrom, and Z = 8. The structure consists of infinite chains run parallel to the c axis and built up of GaO4 tetrahedral and BO3 triangles. The basic unit of these chains is a six - membered Ga2BO8 ring formed by two GaO4 tetrahedra and one BO3 triangles. The Sr atom is bonded to eight oxygen atoms. The strontium atoms serve to hold the chains together through co-ordination with oxygen atoms. DTA curve of noncrystalline glassy SrGaBO4 was discussed. The XRD results show no phase transition occurs between -173degreesC and 127degreesC.
