LaSiP3 crystallizes in the orthorhombic Pbca space group. La(1) is bonded in a 9-coordinate geometry to one P(2), four equivalent P(1), and four equivalent P(3) atoms. Si(1) is bonded to one P(3) and three equivalent P(2) atoms to form corner-sharing SiP4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded in a distorted square co-planar geometry to four equivalent La(1) atoms. In the second P site, P(2) is bonded in a distorted rectangular see-saw-like geometry to one La(1) and three equivalent Si(1) atoms. In the third P site, P(3) is bonded to four equivalent La(1) and one Si(1) atom to form a mixture of distorted corner and edge-sharing PLa4Si trigonal bipyramids.
LaSiP3 crystallizes in the orthorhombic Pbca space group. La(1) is bonded in a 9-coordinate geometry to one P(2), four equivalent P(1), and four equivalent P(3) atoms. The La(1)-P(2) bond length is 3.15 Å. There are a spread of La(1)-P(1) bond distances ranging from 3.11-3.13 Å. There are a spread of La(1)-P(3) bond distances ranging from 2.99-3.06 Å. Si(1) is bonded to one P(3) and three equivalent P(2) atoms to form corner-sharing SiP4 tetrahedra. The Si(1)-P(3) bond length is 2.20 Å. There is one shorter (2.24 Å) and two longer (2.27 Å) Si(1)-P(2) bond lengths. There are three inequivalent P sites. In the first P site, P(1) is bonded in a distorted square co-planar geometry to four equivalent La(1) atoms. In the second P site, P(2) is bonded in a distorted rectangular see-saw-like geometry to one La(1) and three equivalent Si(1) atoms.
