SrTaWMo crystallizes in the trigonal R3m space group. Sr(1) is bonded in a single-bond geometry to one Ta(1), four equivalent W(1), and three equivalent Mo(1) atoms. The Sr(1)-Ta(1) bond length is 0.92 Å. There are three shorter (2.78 Å) and one longer (3.60 Å) Sr(1)-W(1) bond length. All Sr(1)-Mo(1) bond lengths are 2.83 Å. Ta(1) is bonded in a single-bond geometry to one Sr(1), three equivalent W(1), and four equivalent Mo(1) atoms. All Ta(1)-W(1) bond lengths are 2.83 Å. There are three shorter (2.78 Å) and one longer (3.60 Å) Ta(1)-Mo(1) bond length. W(1) is bonded in a 11-coordinate geometry to four equivalent Sr(1), three equivalent Ta(1), and four equivalent Mo(1) atoms. There are three shorter (2.78 Å) and one longer (3.60 Å) W(1)-Mo(1) bond length. Mo(1) is bonded in a 11-coordinate geometry to three equivalent Sr(1), four equivalent Ta(1), and four equivalent W(1) atoms.
