Nb As Ru Pt
NbRuPtAs crystallizes in the trigonal R3m space group. Nb(1) is bonded in a distorted single-bond geometry to three equivalent Ru(1), one Pt(1), and four equivalent As(1) atoms. All Nb(1)-Ru(1) bond lengths are 2.74 Å. The Nb(1)-Pt(1) bond length is 1.83 Å. There are three shorter (2.74 Å) and one longer (2.75 Å) Nb(1)-As(1) bond length. Ru(1) is bonded in a 7-coordinate geometry to three equivalent Nb(1), three equivalent Pt(1), and one As(1) atom. All Ru(1)-Pt(1) bond lengths are 2.74 Å. The Ru(1)-As(1) bond length is 1.83 Å. Pt(1) is bonded in a single-bond geometry to one Nb(1), three equivalent Ru(1), and three equivalent As(1) atoms. All Pt(1)-As(1) bond lengths are 2.74 Å. As(1) is bonded in a 8-coordinate geometry to four equivalent Nb(1), one Ru(1), and three equivalent Pt(1) atoms.
