文摘

Single crystals of a novel lead calcium borate, PbCaB₂O₅, have been successfully grown by spontaneous crystallization method for the first time. The single-crystal X-ray structural analysis showed that PbCaB₂O₅ crystallizes in the triclinic space group P with a?=?3.6736(6) ?, b?=?6.5363(11) ?, c?=?9.7585(17) ?,?¦Á?=?100.504(2)¡ã, ¦Â?=?90.752(2)¡ã, ¦Ã?=?91.627(2)¡ã, and Z?=?2. The crystal structure consists of isolated B₂O₅ units, PbO₅ and Pb/CaO₇ polyhedra. Spectrum properties of PbCaB₂O₅ were reported.
