Synthesis, spectral properties, crystal structures and antimicrobial effects of copper(II) pyridinecarboxylate adducts with chelating ligands

Crystal structure, spectroscopic and magnetic properties, and antimicrobial activities of cobalt(II) 2-methylthionicotinate complexes with N-heterocyclic ligands

“…Synthesis, spectroscopic, magnetic and thermal properties as well as crystal structures of various complexes MX 2 Á nH 2 O (where M is Cu or Co; X is nic, isonic, 2-MeSnic or 2,6-(MeO) 2 nic; n = 0-13) have been reported [14][15][16][17][18][19]. The reaction of metal(II) salt with nic or isonic in aqueous solution leads to formation of monomeric octahedral complexes [MX 2 (H 2 O) 4 ] with supramolecular structures [8,9].…”

“…Recently, synthesis, spectroscopic and magnetic properties as well as crystal structures of the adducts of the above Cu(II) pyridinecarboxylates with chelating and Nheterocyclic ligands were studied [19][20][21][22][23]. Different coordination modes of the pyridinecarboxylate (coordinated not only through the carboxylate group, but also through the nitrogen atom of the pyridine ring) lead to formation of mononuclear, dimeric or polynuclear structures [19][20][21][22][23].…”

Hydrothermal synthesis, crystal structure and strong blue fluorescence of a novel 3D coordination polymer containing copper and zinc centers linked by isonicotinic acid ligands

“…In 1994, a 3D framework metal phosphonate b-Cu(O 3 PCH 3 ) with a 1D channel was first reported by Le Bideau and coworkers [4]. Since then great efforts in metal-organic networks have been mostly focused on coordination polymers with organic rod-like rigid group ligands containing either Ndonor or O-donor ones, while the isonicotinic acid (HIN) ligand is a combination of these nature and has shown interesting properties [5][6][7][8][9][10][11]. At present, a large number of MOF structures containing IN lignds have been designed, such as [Cu(IN) AE H 2 O] [7], [Cu 3 (CN)(IN) 2 ] n [8], [(Cu 2 I)(IN) 2 ] 1 [9], [Zn(IN) 2 AE 2H 2 O] [1], [Cu(en) 2 (H 2 O) 2 ] X 2 AE nH 2 O (where X is nicotinate (n = 0) or isonicotinate (n = 4)) [10] and [Ln 14 (l 6 -O)(l 3 -OH) 20 (IN) 22 Cu 6 C 14 -(H 2 O) 8 ] AE 6H 2 O [Ln = Y, Gd or Dy] [11] etc.…”
