Ca2Zn is zeta iron carbide structured and crystallizes in the tetragonal P4_2/mnm space group. Ca(1) is bonded in a 3-coordinate geometry to three equivalent Zn(1) atoms. Zn(1) is bonded to six equivalent Ca(1) atoms to form a mixture of corner and edge-sharing ZnCa6 octahedra. The corner-sharing octahedral tilt angles are 41°.
Ca2Zn is zeta iron carbide structured and crystallizes in the tetragonal P4_2/mnm space group. Ca(1) is bonded in a 3-coordinate geometry to three equivalent Zn(1) atoms. There is one shorter (2.98 Å) and two longer (3.03 Å) Ca(1)-Zn(1) bond lengths. Zn(1) is bonded to six equivalent Ca(1) atoms to form a mixture of corner and edge-sharing ZnCa6 octahedra. The corner-sharing octahedral tilt angles are 41°.
