BaNiGaSn crystallizes in the trigonal R3m space group. Ba(1) is bonded in a distorted single-bond geometry to three equivalent Ni(1), three equivalent Ga(1), and one Sn(1) atom. All Ba(1)-Ni(1) bond lengths are 3.65 Å. All Ba(1)-Ga(1) bond lengths are 2.99 Å. The Ba(1)-Sn(1) bond length is 2.12 Å. Ni(1) is bonded in a distorted single-bond geometry to three equivalent Ba(1), one Ga(1), and three equivalent Sn(1) atoms. The Ni(1)-Ga(1) bond length is 2.12 Å. All Ni(1)-Sn(1) bond lengths are 2.99 Å. Ga(1) is bonded to three equivalent Ba(1), one Ni(1), and one Sn(1) atom to form corner-sharing GaBa3NiSn trigonal bipyramids. The Ga(1)-Sn(1) bond length is 2.12 Å. Sn(1) is bonded in a distorted linear geometry to one Ba(1), three equivalent Ni(1), and one Ga(1) atom.
