The structure described by YVFe11H crystallizes in the orthorhombic Imm2 space group. Y(1) is bonded in a distorted linear geometry to one V(1), two equivalent Fe(6), eight equivalent Fe(4), and two equivalent H(1) atoms. V(1) is bonded in a 14-coordinate geometry to one Y(1), one Fe(5), two equivalent Fe(2), two equivalent Fe(3), four equivalent Fe(4), and four equivalent Fe(6) atoms. There are six inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a single-bond geometry to two equivalent Fe(6), four equivalent Fe(4), and one H(1) atom. In the second Fe site, Fe(2) is bonded in a distorted single-bond geometry to two equivalent V(1), two equivalent Fe(6), four equivalent Fe(4), and one H(1) atom. In the third Fe site, Fe(3) is bonded in a single-bond geometry to one V(1), two equivalent Fe(6), four equivalent Fe(4), and one H(1) atom. In the fourth Fe site, Fe(4) is bonded to two equivalent Y(1), one V(1), one Fe(1), one Fe(2), one Fe(5), two equivalent Fe(3), two equivalent Fe(4), and two equivalent Fe(6) atoms to form distorted FeY2VFe9 cuboctahedra that share corners with ten equivalent Fe(4)Y2VFe9 cuboctahedra, corners with two equivalent H(1)Y2Fe4 octahedra, edges with four equivalent Fe(4)Y2VFe9 cuboctahedra, faces with six equivalent Fe(4)Y2VFe9 cuboctahedra, and faces with two equivalent H(1)Y2Fe4 octahedra. The corner-sharing octahedral tilt angles range from 68-69°. In the fifth Fe site, Fe(5) is bonded in a distorted single-bond geometry to one V(1), four equivalent Fe(4), and four equivalent Fe(6) atoms. In the sixth Fe site, Fe(6) is bonded in a 14-coordinate geometry to one Y(1), two equivalent V(1), one Fe(1), one Fe(2), one Fe(6), two equivalent Fe(3), two equivalent Fe(5), and four equivalent Fe(4) atoms. H(1) is bonded to two equivalent Y(1), one Fe(1), one Fe(2), and two equivalent Fe(3) atoms to form HY2Fe4 octahedra that share corners with eight equivalent Fe(4)Y2VFe9 cuboctahedra, corners with two equivalent H(1)Y2Fe4 octahedra, and faces with eight equivalent Fe(4)Y2VFe9 cuboctahedra. The corner-sharing octahedral tilt angles are 2°. is represented by the Crystallographic Information File (CIF) [CIF]
