Re2P crystallizes in the orthorhombic Pnma space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 2-coordinate geometry to four equivalent P(1) atoms. In the second Re site, Re(2) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. P(1) is bonded in a 7-coordinate geometry to three equivalent Re(2) and four equivalent Re(1) atoms.
Re2P crystallizes in the orthorhombic Pnma space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 2-coordinate geometry to four equivalent P(1) atoms. There are two shorter (2.32 Å) and two longer (2.74 Å) Re(1)-P(1) bond lengths. In the second Re site, Re(2) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. There is one shorter (2.37 Å) and two longer (2.57 Å) Re(2)-P(1) bond lengths. P(1) is bonded in a 7-coordinate geometry to three equivalent Re(2) and four equivalent Re(1) atoms.
