RuSnSb crystallizes in the trigonal R3m space group. Ru(1) is bonded in a single-bond geometry to four equivalent Sn(1) and one Sb(1) atom. There are three shorter (2.72 Å) and one longer (3.55 Å) Ru(1)-Sn(1) bond length. The Ru(1)-Sb(1) bond length is 0.40 Å. Sn(1) is bonded to four equivalent Ru(1) and three equivalent Sb(1) atoms to form a mixture of edge and corner-sharing SnSb3Ru4 hexagonal pyramids. All Sn(1)-Sb(1) bond lengths are 2.71 Å. Sb(1) is bonded in a single-bond geometry to one Ru(1) and three equivalent Sn(1) atoms.
