title: 2,2'-Bis(ferrocenylmethyl)-5,5'-(m-phenyl-ene)di-2H-tetra-zole.
abstract: In the title compound, [Fe(2)(C(5)H(5))(2)(C(20)H(16)N(8))], one of the unsubstituted cyclo-penta-diene (Cp) rings is disordered over two positions, with site-occupancy factors of 0.609 (19) and 0.391 (19). The dihedral angle formed by the benzene ring with the tetra-zole rings are 51.86 (15) and 3.76 (11)°. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by inter-molecular C-H⋯N hydrogen-bonding inter-actions.
