La7Ru3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent La sites. In the first La site, La(1) is bonded to two equivalent Ru(1) and two equivalent Ru(2) atoms to form a mixture of distorted edge and corner-sharing LaRu4 tetrahedra. In the second La site, La(2) is bonded in a 3-coordinate geometry to three equivalent Ru(2) atoms. In the third La site, La(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Ru(1) atoms. In the fourth La site, La(4) is bonded in a 2-coordinate geometry to one Ru(1) and two equivalent Ru(2) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a 7-coordinate geometry to two equivalent La(1), two equivalent La(4), and three equivalent La(2) atoms. In the second Ru site, Ru(1) is bonded in a 8-coordinate geometry to two equivalent La(3), two equivalent La(4), and four equivalent La(1) atoms.

In the first La site, La(1) is bonded to two equivalent Ru(1) and two equivalent Ru(2) atoms to form a mixture of distorted edge and corner-sharing LaRu4 tetrahedra. Both La(1)-Ru(1) bond lengths are 3.04 Å. There is one shorter (3.10 Å) and one longer (3.11 Å) La(1)-Ru(2) bond length. In the second La site, La(2) is bonded in a 3-coordinate geometry to three equivalent Ru(2) atoms. There are a spread of La(2)-Ru(2) bond distances ranging from 2.92-3.18 Å. In the third La site, La(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Ru(1) atoms. There is one shorter (2.75 Å) and one longer (2.88 Å) La(3)-Ru(1) bond length. In the fourth La site, La(4) is bonded in a 2-coordinate geometry to one Ru(1) and two equivalent Ru(2) atoms. The La(4)-Ru(1) bond length is 3.47 Å. There is one shorter (2.76 Å) and one longer (2.90 Å) La(4)-Ru(2) bond length. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a 7-coordinate geometry to two equivalent La(1), two equivalent La(4), and three equivalent La(2) atoms. In the second Ru site, Ru(1) is bonded in a 8-coordinate geometry to two equivalent La(3), two equivalent La(4), and four equivalent La(1) atoms.
