“…Ru II (Ariel et al, 1984), Ru III (James et al, 1984), Ru IV (Maeda et al, 2015) or Ru VI (Katsunori et al, 2012), and it is able to coordinate one or two small axial ligands, such as aqua, hydroxide, dinitrogen, nitrite, nitrosyl, carbonyl, methanol, ethanol, tetrahydrofuran, pyridine and many others, as can be found from a search in the Cambridge Structural Database (ConQuest, Version 1.18 with updates; Groom et al, 2016), which gave 225 hits. The structural diversity of ruthenium complexes, which can also form metal-metal bonds (Collman et al, 1984), offers an opportunity to use them in the design of multifunctional supramolecular assemblies (Mamardashvili et al, 2013).…”

Porphyrin complexes of ruthenium are widely used as models for the heme protein system, for modelling naturally occurring iron-porphyrin systems and as catalysts in epoxidation reactions. The structural diversity of ruthenium complexes offers an opportunity to use them in the design of multifunctional supramolecular assemblies. Coproporphyrins and metallocoproporphyrins are used as sensors in bioassay and the potential use of derivatives as multiparametric sensors for oxygen and H is one of the main factors driving a growing interest in the synthesis of new porphyrin derivatives. In the coproporphyrin I Ru complex catena-poly[[carbonylruthenium(II)]-μ-2,7,12,17-tetrakis[2-(ethoxycarbonyl)ethyl]-3,8,13,18-tetramethylporphyrinato-κN,N',N'',N''':O], [Ru(CHNO)(CO)], the Ru centre is coordinated by four N atoms in the basal plane, and by axial C (carbonyl ligand) and O (ethoxycarbonylethyl arm from a neighbouring complex) atoms. The complex adopts a distorted octahedral geometry. Self-assembly of the molecules during crystallization from a methylene chloride-ethanol (1:10 v/v) solution at room temperature gives one-dimensional polymeric chains.

“…Maher et al have investigated the electrochemical and electron-electron exchange interactions in molybdenum complexes with 4IP [5]. Mamardashvili et al have synthesized and identified complexes of 4IP with Ru(II) and Sn(IV) tetraphenylporphyrins [6]. In that study it is reported that 4IP binds to Ru(II) center via its imidazolic nitrogen and binds to Sn(IV) center via its hydroxyl group.…”

“…The involved organic bases were used taking into account the remarkable antibacterial, anti-tumour, antiischemic and anti-allergic properties of medications having the substrates in the structure [14,15], and an ability of concerned organic bases to be readily coordinated by transition metal ions [7][8][9][16][17][18][19][20]. The presence of the axially coordinated base as part of the coordination sphere of the macrocyclic complexes can significantly affect the biological and catalytic activity of both substrates and the molecular complex as a whole.…”

ABSTRACT:The interaction of (chloro)-m-nitrido-bis[(tetra-tert-butyl-phthalocyaninato)iron(IV)] Cl(FePc) 2 N with organic N-bases L as electron-donors (L = diethylamine, imidazole, 1-methylimidazole, 2-methylimidazole) with the formation of one-electron reduced species (L)PcFe III -N=Fe IV Pc(L) was investigated in benzene at 298 K by UV-visible spectroscopy. The reaction was established to be stepwise process including fast reversible axial binding of two substrate molecules onto iron cations followed by slow one-electron metal-centered reduction. The results of IR, ESI-MS and EPR study support the formation of final product with Fe +3 -N=Fe +4 unit and two substrate molecules in the first coordination sphere. The reaction kinetics was studied, the pre-equilibrium constants K eq and rate constants k were obtained. The K eq and k values were found to be linearly correlated with basicity of substrates pК a . The possibility of the transition Fe 4+ → Fe 3+ is promoted by electron-donor properties of substrate combined with the presence of both electron-rich macrocycle and p-backdonation Fe ← N Pc .
