NbFeGaSn crystallizes in the trigonal R3m space group. Nb(1) is bonded in a distorted linear geometry to one Fe(1), three equivalent Ga(1), and four equivalent Sn(1) atoms. The Nb(1)-Fe(1) bond length is 2.07 Å. All Nb(1)-Ga(1) bond lengths are 2.71 Å. There is one shorter (2.33 Å) and three longer (2.96 Å) Nb(1)-Sn(1) bond lengths. Fe(1) is bonded in a 1-coordinate geometry to one Nb(1), one Ga(1), and three equivalent Sn(1) atoms. The Fe(1)-Ga(1) bond length is 2.33 Å. All Fe(1)-Sn(1) bond lengths are 2.71 Å. Ga(1) is bonded in a 7-coordinate geometry to three equivalent Nb(1), one Fe(1), and three equivalent Sn(1) atoms. All Ga(1)-Sn(1) bond lengths are 2.71 Å. Sn(1) is bonded in a 10-coordinate geometry to four equivalent Nb(1), three equivalent Fe(1), and three equivalent Ga(1) atoms.
