XRD study of solid-phase interaction in the Li{sub 2}MoO{sub 4}-K{sub 2}MoO{sub 4}-In{sub 2}(MoO{sub 4}){sub 3} system was performed. The boundary K{sub 2}MoO{sub 4}-In{sub 2}(MoO{sub 4}){sub 3} system is an non-quasibinary join of the K{sub 2}O-In{sub 2}O{sub 3}-MoO{sub 3} system where a new polymolybdate K{sub 3}InMo{sub 4}O{sub 15} isotypic to K{sub 3}FeMo{sub 4}O{sub 15} was found. In the structure (a=33.2905(8), b=5.8610(1), c=15.8967(4) A, {beta}=90.725(1) Degree-Sign , sp. gr. C2/c, Z=8, R(F)=0.0407), InO{sub 6} octahedra, Mo{sub 2}O{sub 7} diortho groups and MoO{sub 4} tetrahedra form infinite ribbons {l_brace}[In(MoO{sub 4}){sub 2}(Mo{sub 2}O{sub 7})]{sup 3-}{r_brace}{sub {infinity}} along the b-axis. Between the chains, 8- to 10-coordinate potassium cations are located. A subsolidus phase diagram of the Li{sub 2}MoO{sub 4}-K{sub 2}MoO{sub 4}-In{sub 2}(MoO{sub 4}){sub 3} system was constructed and a novel triple molybdate LiK{sub 2}In(MoO{sub 4}){sub 3} was revealed. Its crystal structure (a=7.0087(2), b=9.2269(3), c=10.1289(3) A, {beta}=107.401(1) Degree-Sign , sp. gr. P2{sub 1}, Z=2, R(F)=0.0280) contains an open framework of vertex-shared MoO{sub 4} tetrahedra, InO{sub 6} octahedra and LiO{sub 5} tetragonal pyramids with nine- and seven-coordinate potassium ions in the framework channels. - Graphical abstract: Exploring the Li{sub 2}MoO{sub 4}-K{sub 2}MoO{sub 4}-In{sub 2}(MoO{sub 4}){sub 3} system showed its partial non-quasibinarity and revealed new compounds K{sub 3}InMo{sub 4}O{sub 15} (isotypic to K{sub 3}FeMo{sub 4}O{sub 15}) and LiK{sub 2}In(MoO{sub 4}){sub 3} which were structurally studied. An open framework of the latter is formed by vertex-shared MoO{sub 4} tetrahedra, InO{sub 6} octahedra and LiO{sub 5} tetragonal pyramids. Highlights: Black-Right-Pointing-Pointer Subsolidus phase relations in the Li{sub 2}MoO{sub 4}-K{sub 2}MoO{sub 4}-In{sub 2}(MoO{sub 4}){sub 3} system were explored. Black-Right-Pointing-Pointer The K{sub 2}MoO{sub 4}-In{sub 2}(MoO{sub 4}){sub 3} system is a non-quasibinary join of the K{sub 2}O-In{sub 2}O{sub 3}-MoO{sub 3} system. Black-Right-Pointing-Pointer New compounds K{sub 3}InMo{sub 4}O{sub 15} and LiK{sub 2}In(MoO{sub 4}){sub 3} were obtained and structurally studied. Black-Right-Pointing-Pointer K{sub 3}InMo{sub 4}O{sub 15} is isotypic to K{sub 3}FeMo{sub 4}O{sub 15} and carries bands of InO{sub 6}, MoO{sub 4} and Mo{sub 2}O{sub 7} units. Black-Right-Pointing-Pointer An open framework of LiK{sub 2}In(MoO{sub 4}){sub 3} is formed by polyhedra MoO{sub 4}, InO{sub 6} and LiO{sub 5}.
