Abstract
The dark brown anti-ferromagnetic modification of (C5H5)2Mn crystallizes ortho-rhombic, space group Pna21 (or Pnam) with a= 1402.7(2), 6 = 582.9(1), c = 996.5(1) pm and Z = 4. It forms polymer chains with a zigzag arrangement of C5H5Mn units and additional bridging C5H5-rings between adjacent ions. The normals to the planes of the C5H5-bridges form an angle of 25° to the Mn-Mn-axes. All Mn-C bond distances are longer than expected for covalent bonds, suggesting essentially ionic bonding in agreement with the magnetic behaviour of (C5H5)2Mn. The observed antiferromagnetism is attributed to interactions between the manganese ions via the C5H5-bridges.
