“…5, where the solvent ligand replaces an equatorial carbonyl, and is based on similar dicarbonyl species. 43,44 Additionally, in a separate irradiation experiment where PPh 3 is present, the phosphine ligand replaces an equatorial carbonyl, rather than the cyanide ligand, which is consistent with the photochemical work done by Gómez et al (Fig. S6 and S7 †).…”

Several heterobinuclear cyanide-bridged cationic complexes of the type [LnM,-CN-M,Ln]+, where LnMl and LnM2 are the fragments Fe(C5H5)(dppe) or cis-or rrans-Mn(CO)z(L-L)L [L-L = dppm, dppe; L = P(OPh),, PEt3; dppe = Ph2P(CH2CHz)PPh2; dppm = Ph,P(CH2)PPhJ, have been prepared as hexafluorophosphate salts by reacting the appropriate mononuclear complexes LnM,-CN and X-MzLn (X = Br, I) in the presence of TIPF6 or (NH4)PF6 as halogen abstractors. The oxidation of these compounds have been studied electrochemically by cyclic voltammetry and chemically by infrared spectroscopy. The results indicated that the first oxidation of the cations affects the Fe or Mn fragment depending on its position relative to the cyanide bridge and the stereochemistry (cis or trans) of the dicarbonyl fragments. When the oxidation affects a cis-Mn(CO),(L-L)L moiety, a very rapid isomerization to the trans form is observed and, in the case of the cis-dicarbonyl complexes [(C5H,)(dppe)Fe-CNMn(CO),(L-L)L]', the first oxidation takes place at Fe but is followed by electron transfer to Mn with concomitant isomerization to the irons-dicarbonyl form.

“…C−H⋅⋅⋅π interaction is found in B and the point‐centroid distances is 3.2562(1) Å, seen in Figure 5. generally speaking, π‐π interactions is one of the weakest interatomic forces which consist in stacks of aromatic groups with the distances of about 3.3–3.8 Å [24–26] . Acrroding to the literature, strong interactions are around 3.3 Å and weaker interactions lie above 3.6 Å with 3.8 Å being approximately the maximum contact [27] .…”

Dinuclear Ni(II) macrocyclic complex A ([Ni2L1OAc]ClO4⋅CH3OH⋅H2O) and dinuclear Ni(II) acyclic complex B ([Ni2L2](ClO4)2) were synthesized by condensation between H2L (3,3′‐(ethane‐1,2‐diylbis(benzylazanediyl))bis(methylene)bis(2‐hydroxy‐5‐methyl‐benzaldehyde)) and different molar equivalent 1,3‐propanediamine in the presence of Ni(II) ions. The structures of complexes were characterized by IR spectroscopy, elemental analysis, electrospray mass spectra and X‐ray single crystal diffraction. In complex A, the Ni(II)‐Ni(II) distance was 2.9413(7) Å, bridged by two phenolic oxygens and an acetate anion, while in complex B, it was 3.0540(1) Å, only bridged by two phenolic oxygens. The calf thymus DNA (CT‐DNA) binding ability was studied through spectroscopic and electrochemical methods, the corresponding binding constant for complexes A and B were 6.45×104 M−1 and 8.65×104 M−1, respectively. The MS revealed that B can transform to A by adding more H2L, and A cannot transform to B in the presence of excess 1,3‐propanediamine.
