The synthesis and metal coordination chemistry of new 1,1′-N-substituted ferrocenediyl ligands derived from 1,1′-diaminoferrocene

A series of 1,1′-N-substituted ferrocenediyl ligands has been synthesised from 1,1′-diaminoferrocene via Schiff base condensation reactions and the coordination chemistry probed by reaction with Zr and Al reagents; an unusual dimetallic, bis-chelate Al complex has been structurally characterised.
