Synthesis and Characterisation of Unsymmetrical Porphyrazines Containing Bis(hydroxyethylthio) Substituents

Summary. Unsymmetrical porphyrazines bearing a single peripheral bis(hydroxyethylthio) moiety were synthesised by mixed condensation of bis(2-hydroxyethylthio)maleonitrile and phthalonitrile. Complexation of the thioether groups of metal-free porphyrazine with PdCl₂ further lowered the intensity of the Q-band absorption of the porphyrazine core. The new compounds were characterised by elemental analyses, IR, ¹H NMR, UV-Vis, and mass spectra.

4,5‐Bis(furoylsulfanyl)‐1,3‐dithiole‐2‐thione

The title compound, C₁₃H₆O₄S₅, possesses crystallographically imposed mirror symmetry, with the atoms of the C=S group lying on the mirror plane. It is an example of the general formula [RCO]₂(dmit), where R is a furan ring and dmit is 2‐thioxo‐1,3‐dithiole‐4,5‐dithiol­ate. The components exhibit some polarization of their mol­ecular–electronic structure. The dmit and furan moieties exhibit a high degree of conjugation, as the introduction of C=O connecting the conjugated furan (donor) and dmit (acceptor) rings forms a good conjugated system with high delocalization. A polar three‐dimensional framework is built from a combination of inter­molecular contacts, namely S⋯S inter­actions and C—H⋯O hydrogen bonding. The structural characteristics lead to good second‐order non‐linear optical properties.     

Synthesis and Characterization of A Nickel(II) Complex With Bis(Benzimidazol-2-Ylmethyl) (2-Hydroxyethyl)Amine

This paper reports the synthesis, crystal structure and properties of two new mononuclear nickel(II) complexes, [NiL(phen)][ClO₄]₂(1) and [NiL(bpy)][ClO₄]₂(2), where L is bis(benzimidazol-2-ylmetheyl)(2-hydroxyethyl)amine and phen and bpy are 1,10-phenanthroline and 2,2'-bipyridine, respectively. The crystal structure of 1 ·2EtOH has been determined by single-crystal X-ray analysis. It crystallizes in the monoclinic system, space group C2/c, a= 24.279(2), b= 20.864(2), c= 17.635(1)Å, g = 121.730(2)°, Z= 8, R ₁= 0.064, wR ₂= 0.167. The Ni(II) ion in 1 ·2EtOH is coordinated to three nitrogen atoms and one oxygen atom of the ligand L and two nitrogen atoms of phen to form a distorted octahedron. Spectroscopic properties of 1 and 2 are reported.     

Transition metal complexes with 1,3-bis-(2-hydroxyphenyl)-1,3-propanedione—I : Mononuclear complexes

Reaction of 1,3-(2-hydroxyphenyl)-1,3-propanedione (BhPPH₃), a ligand with three possible sites of coordination acting as a chelating agent, with metal acetates results in the formation of mononuclear species M(BhPPH₂)₂S,S′ (M=Mn, Fe, Co, Ni, Zn; S,S′=CH₃OH, C₂H₅OH or H₂O); M′(BhPPH₂)₂ (M′=Cu, Pd), and M″(BhPPH₂)₃S,S′ (M″= Fe, Al). The complexes have been studied by ¹H-NMR when possible, and IR spectra. The position of the methine proton (=CH-) at 6.88 ppm in Zn(BhPPH₂)₂S,S′ indicates that BhPPH₃ behaves in mononuclear complexes as a common β-diketone. Most of the complexes lose S,S′ molecules on heating but a crystal structure of Zn(BhPPH₂)₂ · 2C₂H₅)OH indicates that the C₂H₅OH molecules are oxygen bonded to the metal centre.
