Ba Ba Ba Ba Re W
Ba4WRe crystallizes in the trigonal R3m space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a bent 120 degrees geometry to three equivalent Ba(2), one W(1), and one Re(1) atom. There are two shorter (3.59 Å) and one longer (4.76 Å) Ba(1)-Ba(2) bond length. The Ba(1)-W(1) bond length is 2.50 Å. The Ba(1)-Re(1) bond length is 2.35 Å. In the second Ba site, Ba(2) is bonded in a 15-coordinate geometry to nine equivalent Ba(1), three equivalent W(1), and three equivalent Re(1) atoms. All Ba(2)-W(1) bond lengths are 4.03 Å. All Ba(2)-Re(1) bond lengths are 4.04 Å. W(1) is bonded in a 3-coordinate geometry to three equivalent Ba(1) and three equivalent Ba(2) atoms. Re(1) is bonded in a trigonal planar geometry to three equivalent Ba(1) and three equivalent Ba(2) atoms.
