摘要：

A　novel　ternary　borate,　sodium　strontium　pentaborate,　NaSrB　5O9,　has　been　prepared　by　solid-state　reaction　below　800　°C.　The　single-crystal　X-ray　structural　analysis　showed　that　NaSrB　5O9　crystallizes　in　monoclinic,　space　group　P2　1/c　with　a　=　6.499(2),　b　=　13.979(3),　c　=　8.045(2)　Å,　β　=　106.92(2)°,　V　=　699.2(3)　Å3,　Z　=　4,　Mr　=　308.66,　Dc　=　2.932　g/cm3,　μ　=　7.804　mm-1,　F(000)　=　584,　R　=　0.0264　and　wR　=　0.0621　for　2426　observed　reflections　and　146　variables.　NaSrB5O9　is　a　layered　compound　containing　double　ring　B5O11　building　units　composed　of　two　BO4　tetrahedra　and　three　BO3　triangles.　Each　B5O11　unit　is　connected　to　four　other　equivalent　units　through　exocyclic　oxygen　atoms　to　form　a　two-dimensional　∞2[B5O　9]3-　layer.　Symmetry-center　related　layers　are　stacked　along　the　b　axis　and　held　together　by　Na+　and　Sr2+　cations　via　electrostatic　interactions.
