New divalent lanthanoid and alkaline earth metal complexes bearing the 1,3-bis(diphenylphosphano)cyclopentadienyl ligand have been synthesised using redox-transmetallation protolysis (RTP) approach. From reaction of corresponding metal, diphenylmercury proligand C5H4(PPh2)2, compounds [M(η5-C5H3(PPh2)2-1,3)2(S)] (with M = Yb, S (thf)2 or Eu, Ca, Sr, Ba, dme) were isolated characterised by X-ray...

The synthesis, electronic and spectroelectrochemical studies of a cyclometalated heteroleptic Ir(iii) complex containing a redox active ferrocenyl imidazophenanthroline ancillary ligand, is presented. Depending on the oxidation state of the ferrocene, controlled by external electrochemical stimuli, the emission fluorescence intensity of this bistable heterometallic complex can be modulated.

A novel bis-imidazolyl tetradentate Schiff base ligand (H2L) has been prepared from the condensation of imidazole2-carbaldehyde and 1,3-diaminopropane. The ligand reacts with copper(II) perchlorate in neutral medium to yield the mononuclear complex [Cu(H2L)(ClO4)]ClO4‚H2O. A single-crystal X-ray diffraction study confirmed the expected structure, C11H16N6O9Cl2Cu, triclinic, P1h, a ) 8.875(2) Å,...

The new dialkyl(aryl) lithium zincates [(THF)(2)Li(C(6)H(4)-OMe)MeZnMe] (4), [(TMEDA)Li(C(6)H(4)-OMe)MeZnMe] (6), [(THF)(3)Li(C(6)H(4)-OMe)(t)BuZn(t)Bu] (7), and [(PMDETA)Li(C(6)H(4)-OMe)(t)BuZn(t)Bu] (8) have been prepared by co-complexation reactions of lithiated anisole with the relevant dialkylzinc compound and the relevant Lewis base. These new heterobimetallic compounds have been characte...
