The material described by In4AsP3 is Chalcopyrite-like structured and crystallizes in the orthorhombic Amm2 space group. There are three inequivalent In sites. In the first In site, In(1) is bonded to two equivalent P(1) and two equivalent P(2) atoms to form InP4 tetrahedra that share corners with two equivalent In(3)As2P2 tetrahedra, corners with two equivalent In(1)P4 tetrahedra, and corners with eight equivalent In(2)AsP3 tetrahedra. In the second In site, In(2) is bonded to one As(1), one P(2), and two equivalent P(1) atoms to form InAsP3 tetrahedra that share corners with four equivalent In(3)As2P2 tetrahedra, corners with four equivalent In(2)AsP3 tetrahedra, and corners with four equivalent In(1)P4 tetrahedra. In the third In site, In(3) is bonded to two equivalent As(1) and two equivalent P(1) atoms to form InAs2P2 tetrahedra that share corners with two equivalent In(3)As2P2 tetrahedra, corners with two equivalent In(1)P4 tetrahedra, and corners with eight equivalent In(2)AsP3 tetrahedra. As(1) is bonded to two equivalent In(2) and two equivalent In(3) atoms to form AsIn4 tetrahedra that share corners with two equivalent As(1)In4 tetrahedra, corners with two equivalent P(2)In4 tetrahedra, and corners with eight equivalent P(1)In4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one In(1), one In(3), and two equivalent In(2) atoms to form PIn4 tetrahedra that share corners with four equivalent As(1)In4 tetrahedra, corners with four equivalent P(1)In4 tetrahedra, and corners with four equivalent P(2)In4 tetrahedra. In the second P site, P(2) is bonded to two equivalent In(1) and two equivalent In(2) atoms to form PIn4 tetrahedra that share corners with two equivalent As(1)In4 tetrahedra, corners with two equivalent P(2)In4 tetrahedra, and corners with eight equivalent P(1)In4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
