Complexation and electrochemical study of 1,5-diselena[5]ferrocenophane: X-ray crystal structures of 1,5-diselena[5]ferrocenophane, and silver, mercury complexes
摘要:
The silver(I) and mercury(II) complexes of 1,5-diselena[5]ferrocenophane (L) have been synthesized. The X-ray crystal structures of L. [AgL2]PF6 and [Hgl(2)L] are reported. The small cavity of the macrocyclic ligand means that the ring must undergo a conformational change to allow coordination, and there is no significant through-space interaction M center dot center dot center dot Fe in any of the complexes. Electrochemical studies showed that no electronic communication between ferrocenylene groups was observed in the silver complex where the through-bond Fe center dot center dot center dot Fe distances are in the range 13.10 (3)-13.27(3) angstrom.
