ReNi4Zn crystallizes in the trigonal R3m space group. Re(1) is bonded in a single-bond geometry to three equivalent Ni(1) and one Zn(1) atom. All Re(1)-Ni(1) bond lengths are 1.79 Å. The Re(1)-Zn(1) bond length is 0.63 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(2) is bonded in a 12-coordinate geometry to nine equivalent Ni(1) and three equivalent Zn(1) atoms. There are six shorter (2.60 Å) and three longer (2.88 Å) Ni(2)-Ni(1) bond lengths. All Ni(2)-Zn(1) bond lengths are 3.14 Å. In the second Ni site, Ni(1) is bonded in a 3-coordinate geometry to one Re(1), two equivalent Ni(1), and three equivalent Ni(2) atoms. Both Ni(1)-Ni(1) bond lengths are 1.66 Å. Zn(1) is bonded in a single-bond geometry to one Re(1) and three equivalent Ni(2) atoms.
