Abstract: Two ferrocene derivatives with pyrazoles appended at their C-4 position to both cyclopentadienyl (Cp) rings have been synthesized, namely, 1,1′-bis(1H-pyrazol-4-yl)ferrocene (H2HL) and 1,1′-bis(3,5-dimethyl-1H-pyrazol-4-yl)ferrocene (H2MeL). In the solid state, these are shown crystallographically to form supramolecular… read more here.
