Hf Ta Mn Pd
HfTaMnPd crystallizes in the trigonal R3m space group. Hf(1) is bonded in a 10-coordinate geometry to three equivalent Ta(1), four equivalent Mn(1), and three equivalent Pd(1) atoms. All Hf(1)-Ta(1) bond lengths are 2.71 Å. There is one shorter (2.42 Å) and three longer (2.93 Å) Hf(1)-Mn(1) bond lengths. All Hf(1)-Pd(1) bond lengths are 2.71 Å. Ta(1) is bonded in a distorted single-bond geometry to three equivalent Hf(1), three equivalent Mn(1), and four equivalent Pd(1) atoms. All Ta(1)-Mn(1) bond lengths are 2.71 Å. There is one shorter (2.42 Å) and three longer (2.93 Å) Ta(1)-Pd(1) bond lengths. Mn(1) is bonded in a distorted single-bond geometry to four equivalent Hf(1), three equivalent Ta(1), and one Pd(1) atom. The Mn(1)-Pd(1) bond length is 1.94 Å. Pd(1) is bonded in a 1-coordinate geometry to three equivalent Hf(1), four equivalent Ta(1), and one Mn(1) atom.
