Na Ta Ga Re
NaTaReGa crystallizes in the trigonal R3m space group. Na(1) is bonded in a 2-coordinate geometry to one Ta(1), one Re(1), and three equivalent Ga(1) atoms. The Na(1)-Ta(1) bond length is 1.98 Å. The Na(1)-Re(1) bond length is 2.40 Å. All Na(1)-Ga(1) bond lengths are 2.71 Å. Ta(1) is bonded in a 1-coordinate geometry to one Na(1) and four equivalent Ga(1) atoms. There is one shorter (2.40 Å) and three longer (2.94 Å) Ta(1)-Ga(1) bond lengths. Re(1) is bonded in a distorted single-bond geometry to one Na(1) and three equivalent Ga(1) atoms. All Re(1)-Ga(1) bond lengths are 2.71 Å. Ga(1) is bonded in a 10-coordinate geometry to three equivalent Na(1), four equivalent Ta(1), and three equivalent Re(1) atoms.
