Synthesis, Crystal Structure and Optical Investigation of the New Phosphates: Na7Mg13Ln(PO4)12 (Ln: La, Eu). -Single crystals of the new title compounds are prepared by reaction of Na2CO3, MgCO3, Ln2O3 (Ln: La, Eu), and NH4H2PO4 using Na2MoO4 as a flux (Pt crucible, 1273 K, 2 h). The isotypic compou
New phosphates, Sr1.9Cu4.1(PO4)4, Sr2Cu(PO4)2, and Sr9.1Cu1.4(PO4)7, were found in the Cu3(PO4)2+Sr3(PO4)2 system at 9003C under air. Sr1.9Cu4.1(PO4)4 crystallizes in an orthorhombic system with a ؍ 15.3695(7) A > , b ؍ 10.3652(4) A > , and c ؍ 7.9425(4) A > . Crystal structures of Sr9.1Cu1.4(
