NdAl2Ga2 crystallizes in the monoclinic C2/m space group. Nd(1) is bonded in a 16-coordinate geometry to eight equivalent Ga(1) and eight equivalent Al(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), one Ga(1), and four equivalent Al(1) atoms. Al(1) is bonded to four equivalent Nd(1) and four equivalent Ga(1) atoms to form a mixture of distorted edge, corner, and face-sharing AlNd4Ga4 tetrahedra.
NdAl2Ga2 crystallizes in the monoclinic C2/m space group. Nd(1) is bonded in a 16-coordinate geometry to eight equivalent Ga(1) and eight equivalent Al(1) atoms. There are a spread of Nd(1)-Ga(1) bond distances ranging from 3.20-3.22 Å. There are four shorter (3.48 Å) and four longer (3.52 Å) Nd(1)-Al(1) bond lengths. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), one Ga(1), and four equivalent Al(1) atoms. The Ga(1)-Ga(1) bond length is 2.50 Å. There are two shorter (2.60 Å) and two longer (2.61 Å) Ga(1)-Al(1) bond lengths. Al(1) is bonded to four equivalent Nd(1) and four equivalent Ga(1) atoms to form a mixture of distorted edge, corner, and face-sharing AlNd4Ga4 tetrahedra.
