Abstract

Received: 17.11.2017; accepted: 06.12.2017; published: 25.12.2017.In this paper, the results of systematic studies of complex molybdate systems M2MoO4–Ln2(MoO4)3–Hf(MoO4)2 (M = Li–Cs, Tl; Ln = La–Lu) are presented. Subsolidus phase diagrams of ternary systems were constructed and new triple molybdates were obtained. The optimum synthesis conditions for polyand monocrystalline form were determined. According to single-crystal data, the structure of one of the representatives of triple molybdates was determined.This work was carried out according to the state assignment BINM SB RAS (project No. 0339-2016-0007.).
