Li5GaO2 crystallizes in the tetragonal P4_122 space group. There are four inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted bent 120 degrees geometry to one Ga(1) and two equivalent O(1) atoms. In the second Li site, Li(2) is bonded in a linear geometry to two equivalent O(1) atoms. In the third Li site, Li(3) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. In the fourth Li site, Li(4) is bonded in a distorted bent 150 degrees geometry to three equivalent Ga(1) and two equivalent O(1) atoms. Ga(1) is bonded in a 7-coordinate geometry to two equivalent Li(1), three equivalent Li(4), and two equivalent Ga(1) atoms. O(1) is bonded to one Li(2), one Li(3), one Li(4), and two equivalent Li(1) atoms to form corner-sharing OLi5 trigonal bipyramids.
Li5GaO2 crystallizes in the tetragonal P4_122 space group. There are four inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted bent 120 degrees geometry to one Ga(1) and two equivalent O(1) atoms. The Li(1)-Ga(1) bond length is 2.62 Å. There is one shorter (1.89 Å) and one longer (1.95 Å) Li(1)-O(1) bond length. In the second Li site, Li(2) is bonded in a linear geometry to two equivalent O(1) atoms. Both Li(2)-O(1) bond lengths are 1.87 Å. In the third Li site, Li(3) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. Both Li(3)-O(1) bond lengths are 1.86 Å. In the fourth Li site, Li(4) is bonded in a distorted bent 150 degrees geometry to three equivalent Ga(1) and two equivalent O(1) atoms. There is one shorter (2.76 Å) and two longer (3.19 Å) Li(4)-Ga(1) bond lengths. Both Li(4)-O(1) bond lengths are 2.04 Å. Ga(1) is bonded in a 7-coordinate geometry to two equivalent Li(1), three equivalent Li(4), and two equivalent Ga(1) atoms. Both Ga(1)-Ga(1) bond lengths are 2.36 Å. O(1) is bonded to one Li(2), one Li(3), one Li(4), and two equivalent Li(1) atoms to form corner-sharing OLi5 trigonal bipyramids.
