FeP2 is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. Fe(1) is bonded to six equivalent P(1) atoms to form a mixture of corner and edge-sharing FeP6 octahedra. The corner-sharing octahedral tilt angles are 55°. P(1) is bonded in a 3-coordinate geometry to three equivalent Fe(1) atoms.
