NaCo_7.38(PO₄)₄Cl₄ in a series of homeotype compounds with stable cationic substructures derived from the sulphohalite archetype

Abstract

In this paper, we present the synthesis and characterization of a Cl-bearing member of the phosphate family of compounds with a tetragonal crystal structure and similar topology in the basic...

Crystal chemistry and predicted ionic conductivity of hydrothermally synthesized Na9Zn2(PO4)4Cl

“…Lately we described NaCo 7.38 (PO 4 ) 4 Cl 4 , a novel Cl-bearing member in a series of structurally related phosphate fluorides. 11 The inclusion of Cl atoms in the crystallization regime has allowed us to obtain one more phosphate chloride and herein we present results of the medium-temperature hydrothermal synthesis, crystal structure and estimated properties for ionic conductivity of Na 9 Zn 2 (PO 4 ) 4 Cl. The title phase is discussed in correlation with the ion conductor Na 9 Zr(PO 4 ) 4 Cl.…”
