“…[3] Tppz is a remarkably versatile electron donor that displays a wide variety of binding modes. [4] In addition, tppz possesses two transterpyridine coordination sites to coordinate towards transition metal ions and lanthanide(III) ions, [3,5] which might be an idea ligand to construct heterometallic 3d-4f coordination complexes. Therefore, [Ni(tppz) 2 ](NO 3 ) 2 was used as the building block to react with Ln(NO 3 ) 3 • 6H 2 O under solvothermal condition to construct heterometallic 3d-4f coordination complexes.…”

Solvothermal reaction of [Ni(tppz) 2 ](NO 3 ) 2 with Ln(NO 3 ) 3 • 6H 2 O afforded a 3d-4f heterometallic coordination complexes [Ni-(tppz) 2 ][Ln(NO 3 ) 5 ] ((where tppz = 2,3,5,6-tetra(2-pyridyl) pyrazine and Ln(III) = Nd (1), Eu (2), Gd (3), Tb (4), Dy (5), Er ( 6)). The complexes were characterized by elemental analysis, infrared spectroscopy, single-crystal X-ray diffraction, and powder X-ray diffraction. Moreover, UV-Vis absorption properties of 1-6 and solid-state luminescence properties of 2 and 4 are also discussed.[a] X.

Dedicated to Professor Dietmar Stalke on the occasion of his 65 th birthdayStarting from sterically encumbered 2,6-di-tert-butylphenyl phosphate (dtbppH 2 ) and co-ligand 3,5-dimethyl pyrazole (dmpz), it is possible to isolate either mono-, di-or tetranuclear copper phosphates by varying the copper source and making attendant changes in the reaction conditions. For example, reaction of copper nitrate with dtbppH 2 and dmpz at 60 °C leads to the isolation of the mononuclear copper phosphate [Cu(dtbppH) 2 (dmpz)(MeOH) 2 ] (1) as the only product. However, the use of copper acetate in place of copper nitrate and conducting the reaction at the room temperature leads to the formation of both dinuclear [Cu(dtbpp)(dmpz) 2 ] 2 (2) and tetranuclear [Cu 2 (dtbpp)(dmpz) 2 (OAc)(MeO)] 2 (3) from the same reaction mixture. Compounds 2 and 3 could be isolated in pure form through fractional crystallization. Copper phosphates 1-3 have been characterized by both analytical and spectroscopic methods including EPR and magnetic measurements. The molecular structures of all three compounds were established through single crystal diffraction studies. Dc magnetic measurements indicate antiferromagnetic interactions between the metal centres in all the compounds.

Stericallyencumbered 2,6‐di‐tert‐butyl phenyl phosphate (dtbppH2) has been employed to synthesize mononuclear and dinuclear complexes, [Cu(bpy) (dtbppH)2(dtbppH2)]·2MeOH (1) and [Cu(phen)(dtbppH)(NO3)]2·2MeOH (2), respectively. Both compounds have been characterized using analytical and spectroscopic methods, including EPR spectral and magnetic measurements. Complexes 1 and 2 revealed weak antiferromagnetic interactions due to intermolecular interactions in the lattice and intradimeric exchange interactions mediated by the O─P─O phosphate bridges, respectively. Complex 1 exhibited an EPR spectrum with hyperfine splitting, while complex 2 exhibited a triplet spectrum. The electrocatalytic activity of 1 and 2 adsorbed on glassy carbon electrodes has been explored for the oxygen reduction reaction (ORR) in PBS.
