Crystallographic and Computational Study of 4'-(Isoquinolin-5-yl)-2,2':6',2''-terpyridine and the Comparison with Its Structural Isomer 4'-(Isoquinolin-4-yl)-2,2':6',2''-terpyridine

J. Granifo, Dominique Toledo, S. Suárez, Ricardo Baggio

Abstract— The title compound consists of a 2,2':6',2"-terpyridine nucleus (tpy) completed by a pendant isoquinoline group (isq) bound at the central pyridine (py) ring. The tpy nucleus departs slightly from planarity, with pylateral–pycentral interplanar angles in the range 2.24(7)°–7.90(7)°, but the isq …

MAGNETIC ANALYSIS OF TWO [COBALT-IMIDAZOLE-CARBOXYLATE] COMPLEXES: ORBITAL CONTRIBUTION

Ramón Arrué, Dominique Toledo, Octavio Peña, Jean‐Yves Pivan et autres

Two coordination complexes, Co(HIMC) 2 (H 2 O) 2 (1) and Co(H 2 IMDC) 2 (H 2 O) 2 (2), were synthesized by mixing the complex precursor Cobalt(II) hexafluoroacetylacetonate (Co(hfacac) 2 ) with 1H-imidazole-4-carboxylic acid (H 2 IMC) and 1H-imidazole-4,5-imidazoledicarboxylic acid (H …

New cobalt(II) coordination polymer based on carboxyphenyl-tpy ligand: Photoluminescence, crystal structures and magnetic properties, without orbital contribution

Dominique Toledo, Octavio Peña, Thierry Roisnel, Jean‐Yves Pivan et autres

One coordination polymer, [Co(3-ctpy)2(H2O)2]n*2nEtOH (1), was synthesized by a solvothermal method mixing the complex precursor cobalt(II) acetylacetonate (Co(acac)2*2H2O) with 4′-(4-carboxyphenyl)-3,2′:6′,3″-terpyridine (3-Hctpy). This paramagnetic complex has been isolated as a neutral, air and thermal stable solid and has been characterized by elemental analysis, …
