The tailoring of smart material properties is one of the challenges in materials science. The unique features of polymers with pendant ferrocene units, either as ferrocenyl or ferrocenediyl groups, provide electrochemical, electronic, optoelectronic, catalytic, and biological properties with potential for applications as smart materials. The possibility to tune or to switch the properties of such materials relies mostly on the redox activity of the ferrocene/ferricenium couple. By switching the redox state of ferrocenyl units - separately or in a cooperative fashion - charge, polarity, color (UV-vis range) and hydrophilicity of polymers, polymer functionalized surfaces and polymer derived networks (sol-gel) may be controlled. In turn, also the vicinity of such polymers influences the redox behavior of the pendant ferrocenyl units allowing for sensing applications by using polymer bound enzymes as triggering units. In this review the focus is set mainly on the literature of the past five years.

“…The in situ generated silanol then reacts with the Mn(III) porphyrinate to produce the corresponding Mn(III) siloxide complex (scheme 7). The driving force for this process is likely the much stronger Si-O vs Si-S bond strength [45,46].…”

Reaction of [Mn(OAc)(TPP)] (TPP = dianion of meso-tetraphenylporphine) with both HSSi i Pr 3 and HSSiPh 3 in the presence of air leads to formation of the corresponding siloxide complexes, [Mn(OSiR 3 )(TPP)] (R = i Pr 3 , Ph), via silyl group transfer from S to O. The new compounds have been fully characterized in solution and the solid state and represent rare examples of Mn(III) porphyrinates containing Lewis basic axial ligands. X-ray crystallographic analyses of both complexes reveal very short Mn-O bond distances consistent with the presence of a siloxide ligand. Investigations of the reaction pathway are consistent with initial reduction of [Mn(OAc)(TPP)] to [Mn II (TPP)] by the silanethiol. Subsequent aerobic oxidation of the reaction mixture is proposed to generate a Mn(III) porphyrinate and the corresponding silanol, which combine to yield the observed siloxide complex. These findings stand in sharp contrast to those of iron(III) porphyrinates, where silanethiolate complexes are stable.

“…Structures with Z' (the number of moieties in the asymmetric unit) higher than one are quite a crystallographic oddity, which has recently attracted attention in the field of crystal structure prediction and study of the intermolecular interactions in crystal packing [18][19][20][21][22]. [Ir(ppy) 2 (acn) 2 ] + /PF 6 − was analyzed using the same approach already used for other complexes [23], organic compounds [24], and salts [25], calculating Hirshfeld surfaces [26][27][28][29] to evaluate the intermolecular interactions and their differences among the similar coordination compounds [30,31].…”

The title compound bis(2-phenylpyridine-C,N’)-bis(acetonitrile)iridium(III)hexafluorophosphate, a six-coordinate iridium(III) complex, crystallizes in the P-1 space group. Iridium is in a distorted octahedral (n = 6) coordination with the N,C’ atoms of two phenylpyridine and the N atoms of two acetonitrile ligands. The peculiarity of this structure is that three independent moieties of the title compound and three PF6− anions, to counterbalance the charge, are observed in the asymmetric unit and this is a rather uncommon fact among the Cambridge Crystallographic Database (CSD) entries. The three couples are almost identical conformers with very similar torsional angles. The packing, symmetry, and space group were accurately analyzed and described also by means of Hirshfeld surface analysis, which is able to underline subtle differences among the three anion/cation couples in the asymmetric unit. The driving force of the packing is the clustering of the aromatic rings and the maximization of acetonitrile:PF6− interactions. The asymmetry of the cluster is the cause of the unusual number of moieties in the asymmetric unit.
