LaRu3Si2 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a 20-coordinate geometry to two equivalent La(1), twelve equivalent Ru(1), and six equivalent Si(1) atoms. Ru(1) is bonded in a distorted square co-planar geometry to four equivalent La(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 6-coordinate geometry to three equivalent La(1) and six equivalent Ru(1) atoms.
