Four functionalized furyl-thiosemicarbazones (NT1 4) treated with divalent metals (Cu, Co, Pt, and Pd) to form the mononuclear metallic complexes of formula [M L 2Cl2] or [M L Cl2] were examined.
Single crystal X-ray diffraction experiments revealed that both resulted in mononuclear chelate complexes of formula [Cu(L1 2(H2O)]·2H2O (A) and [Co(L3)(H2O)2] (B).
New FeII complexes of formula [Fe 3-Br-phen)2(NCS)2]·Solvent (Solvent=0.5 CH3OH (1), 2 CH2Cl2 (2), desolvation oFe 3-Br-phen CH3COCH3 (4) and 0 (5)) have been synthesized.
Reaction of phosphine-amino-alcohol ligands with [RuCl2 DMSO 4] gave, after purification, the diastereomeric complexes of formula [RuCl2 PNOH)(DMSO ], 5 and 6 in unoptimised yields of 67-78% (Scheme 2).
Two new supramolecular synthon induced single crystals of metal-orotato complexes of formula [Cu(Orotate)·2H2O]2 (1), [Mn(Orotate)2·2H2O]·2H2O] (2), have been engineered and synthesized by self-assembly of metal salts with orotic acid in presence of 25% ammonia solution.
The design and preparation of stable cyanide-bearing six-coordinate complexes of formula [MIII(L)(CN x](x + l − m)− (M = trivalent transition metal ion and L = polydentate blocking ligand) are summarized here.
Three new gadolinium III) complexes of formula [Gd4 bta 3(H2O)16]n·12nH2O (1), [Gd4 bta 3(H2O)12]n·18nH2O (2) and [Gd2(H2bta)(bta)(H2O 2]n·4nH2O (3) (H4bta = 1,2,4,5-benzenetetracarboxylic 1,2,4,5-benzenetetracarboxylicd their structures determined by X-racidiffraction. 1 and 3 are thave-dimensional compounds whereas 2 exhibeen a two-dimensynthesizedcture.
A novel series of copper II) complexes of formula [Cu tren)(mpda)](ClO4 2 · 1/2H2O (1), [Cu2 tren)2(mpda)](ClO4 4 · 2H2O (2), and [Cu2 tren)2(ppda)](ClO4 4 · 2H2O (3) containing the tetradentate tris 2-aminoethyl)amine (tris 2-aminoethylgaminend trenpoterminaly bridging 1,n-phenyligandandne [n = 3 (mpda) and 4 (ppda)] ligand have been prepared and specthescopotentiallyracterized.
