The compound described by W2C is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. W(1) is bonded in a 3-coordinate geometry to three equivalent C(1) atoms. C(1) is bonded to six equivalent W(1) atoms to form a mixture of corner and edge-sharing CW6 octahedra. The corner-sharing octahedral tilt angles are 50°. is represented by the CIF file [CIF]
