Hf Mn Nb Pt
HfNbMnPt crystallizes in the trigonal R3m space group. Hf(1) is bonded in a distorted linear geometry to three equivalent Nb(1), one Mn(1), and four equivalent Pt(1) atoms. All Hf(1)-Nb(1) bond lengths are 2.71 Å. The Hf(1)-Mn(1) bond length is 2.03 Å. There is one shorter (2.36 Å) and three longer (2.95 Å) Hf(1)-Pt(1) bond lengths. Nb(1) is bonded in a 7-coordinate geometry to three equivalent Hf(1), one Mn(1), and three equivalent Pt(1) atoms. The Nb(1)-Mn(1) bond length is 2.36 Å. All Nb(1)-Pt(1) bond lengths are 2.71 Å. Mn(1) is bonded in a 5-coordinate geometry to one Hf(1), one Nb(1), and three equivalent Pt(1) atoms. All Mn(1)-Pt(1) bond lengths are 2.71 Å. Pt(1) is bonded in a 10-coordinate geometry to four equivalent Hf(1), three equivalent Nb(1), and three equivalent Mn(1) atoms.
