NbRhHgZn crystallizes in the trigonal R3m space group. Nb(1) is bonded in a 5-coordinate geometry to three equivalent Rh(1), four equivalent Hg(1), and one Zn(1) atom. All Nb(1)-Rh(1) bond lengths are 2.71 Å. There is one shorter (2.40 Å) and three longer (2.94 Å) Nb(1)-Hg(1) bond lengths. The Nb(1)-Zn(1) bond length is 1.97 Å. Rh(1) is bonded in a 10-coordinate geometry to three equivalent Nb(1), three equivalent Hg(1), and four equivalent Zn(1) atoms. All Rh(1)-Hg(1) bond lengths are 2.71 Å. There is one shorter (2.40 Å) and three longer (2.94 Å) Rh(1)-Zn(1) bond lengths. Hg(1) is bonded in a 10-coordinate geometry to four equivalent Nb(1), three equivalent Rh(1), and three equivalent Zn(1) atoms. All Hg(1)-Zn(1) bond lengths are 2.71 Å.
