The crystal structure of the title compound containing lutetium, the last element in the lanthanide series, was determined using a single crystal prepared by heating a pressed pellet of a 2:1 molar ratio mixture of LuO and AlO powders in an Ar atmosphere at 2173 K for 4 h. LuAlO is isostructural with EuAlO and composed of AlO di-tetra-hedra and Lu-centered six- and sevenfold oxygen polyhedra. The unit-cell volume, 787.3 (3) Å, is the smallest among the volumes of the rare-earth () aluminates, AlO. The crystal studied was refined as a two-component pseudo-merohedric twin.
通过在氩气气氛中于2173 K加热由氧化镥（LuO）和氧化铝（AlO）粉末按2:1摩尔比混合压制而成的小球4小时制备的单晶，确定了含有镧系元素中最后一个元素镥的标题化合物的晶体结构。LuAlO与EuAlO同构，由AlO双四面体和以Lu为中心的六配位和七配位氧多面体组成。晶胞体积为787.3 (3) Å，是稀土（）铝酸盐AlO的体积中最小的。所研究的晶体被精修为两组分假纯形孪晶。
