Fe Fe Ag Ru
RuFe2Ag crystallizes in the monoclinic P2 space group. Ru(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Fe(1) and two equivalent Fe(2) atoms. Both Ru(1)-Fe(1) bond lengths are 3.21 Å. Both Ru(1)-Fe(2) bond lengths are 1.44 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 10-coordinate geometry to two equivalent Ru(1), six equivalent Fe(1), and two equivalent Ag(1) atoms. There are four shorter (2.66 Å) and two longer (3.00 Å) Fe(1)-Fe(1) bond lengths. Both Fe(1)-Ag(1) bond lengths are 2.95 Å. In the second Fe site, Fe(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ru(1) and two equivalent Ag(1) atoms. Both Fe(2)-Ag(1) bond lengths are 2.95 Å. Ag(1) is bonded in a 10-coordinate geometry to two equivalent Fe(1), two equivalent Fe(2), and six equivalent Ag(1) atoms. There are four shorter (2.66 Å) and two longer (3.00 Å) Ag(1)-Ag(1) bond lengths.
