用助熔剂法合成了NaR3+（WO4）2钨酸盐（R3 += Fe，Sc，Ga，In）的单晶，并对其进行了光学测角、X射线衍射和差热分析。这些化合物彼此是同构的。详细研究了NaIn（WO4）2的晶体结构.它与天然黑钨矿的结构相似，但钠和铟构成平行于c轴的不同文件。空间群为P2c。
Single crystals of the NaR 3+(WO 4) 2 tungstates for R 3+= Fe, Sc, Ga and In have been obtained by the flux method and have been investigated by optical goniometry, X-ray analysis, and DTA. The compounds are isostructural with each other. The NaIn (WO 4) 2 crystal structure has been studied in detail. It is similar to the structure of the natural wolframite, but sodium and indium constitute distinct files parallel to the c axis. Space group is P2 c.
