The material described by PuSi is delta Molybdenum Boride-like structured and crystallizes in the orthorhombic Pnma space group. Pu(1) is bonded in a 7-coordinate geometry to seven equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to seven equivalent Pu(1) and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
