AbstractTwo new structurally related cesium manganese vanadates have been synthesized by a high-temperature (580 °C) hydrothermal synthetic method utilizing halide brine mineralizers. Both structures Cs6Mn(H2O)2(VO3)8(I) and Cs5KMn(H2O)2(VO3)8(II) are isostructural crystallizing in the tetragonal space groupP4/mnc. The first structure, Cs6Mn(H2O)2(VO3)8(I) has unit cell dimensions ofa= 13.6830(4) Å,c= 8.6476(3) Å and the second structure, Cs5KMn(H2O)2(VO3)8(II), has unit cell dimensions ofa= 13.5015(4) Å,c= 8.5372(3) Å. The structures are built from a manganese vanadate chain, which consists of [Mn(H2O)2O4] units that are coordinated to one another by a unique sinusoidal vanadate chain, (VO3)n. Both structures have well-ordered alkali metal atoms, with the potassium atoms ofIIexhibiting preferential site occupancy. Both compounds were characterized by single crystal X-ray diffraction and infrared spectroscopy, to identify the characteristic O–H and V–O modes.Graphical AbstractCrystals of Cs6Mn(H2O)2(VO3)8and Cs5KMn(H2O)2(VO3)8were synthesized from hydrothermal brines and their structures determined by single crystal X-ray diffraction, revealing preferential, ordered site substitution of the alkali metals.
