Synthesis and characterization of CsZnVO-a new vanadate in the Cs-Zn-V-O quaternary system
A novel congruent melting compound Cs 2 Zn 4 V 4 O 15 has been synthesized by conventional high-temperature solid-state reactions. The compound crystallizes in the monoclinic system, C 2/ c (No. 15) space group, with a = 15.724(4) Å, b = 5.3548(15) Å, c = 20.921(6) Å, β = 102.572(11)°, V = 1719.3(8)...
