In the title coordination polymer, {[CdBr2(C5H9NO2)]·H2O} n , the Cd(II) ion is coordinated by four bromido ligands and two carboxyl-ate oxygen atoms of two symmetry-related proline ligands, which exist in a zwitterionic form, in a distorted octa-hedral geometry. There is an intra-molecular N-H⋯O hydrogen bond between the amino group and the carboxyl-ate fragment. Each coordinating ligand bridg...

In the mononuclear title complex, [CdBr2(C20H17N3)(C3H7NO)], synthesized from the quinoline-derived Schiff base 2-(1H-indol-3-yl)-N-(quinolin-2-yl-methyl-ene)ethan-amine (IQME), the coordination geometry around the Cd(2+) atom is distorted trigonal bipyramidal, the axial positions being occupied by the quinoline N atom [Cd-N = 2.401 (3) Å] and one di-methyl-formamide O-atom donor [Cd-O = 2.399 ...

A tetrathiafulvalene (TTF) derivative bearing four peripheral 4-picolylthio units has been synthesized and employed for the formation of coordination assemblies with a series divalent metal salts, highlighting flexibility adaptability this ligand owing to rotation allowed around sulfur carbon atoms thiomethyl spacer. While [2 + 1] metallamacrocycle obtained tetrahedral Zn(NCS)2 node, 1D network...

The title compounds, [CdBr2(C12H10N4O)]·CH3OH, (I), and [CdI2(C12H10N4O)], (II), are cadmium bromide and cadmium iodide complexes of the ligand (E)-N'-(pyridin-2-yl-methyl-ene)picolinohydrazide. Complex (I) crystallizes as the methanol monosolvate. In both compounds, the Cd2+ cation is ligated by one O atom and two N atoms of the tridentate ligand, and by two bromide anions forming a Br2N2O pen...

The synthesis and structures of metal aminocarboxylates prepared in acidic, neutral, or alkaline media have been explored with the purpose of isolating coordination polymers with linear chain and two-dimensional layered structures. Metal glycinates of the formulae [CoCl2(H2O)2(CO2CH2NH3)] (I), [MnCl2(CO2CH2NH3)2] (II), and [Cd3Cl6(CO2CH2NH3)4] (III) with one-dimensional chain structures have be...

Ethopropazine (EP) or profenamine is a phenothiazine derivative, N-(2-diethylaminopropyl)phenothiazine (Figure.1), used as an antiparkinsonian drug that has anticholinergic, antihistamine, and antiadrenergic actions. Transition metal complexes of ZnBr2, CdBr2, CdI2, and HgBr2 have been synthesized using EP as the main ligand and purified by recrystallization in MeOH. These products have been ch...

N(1)-Hexyl substituted pyrimidines were shown to present solubility properties closer to the real bases than the commonly used methyl and ethyl derivatives, yielding bi-layered structures in the solid state. The study of their coordination capabilities, mainly with Ag(I) and Hg(II), is presented in order to prove their reactivity. A series of coordination complexes, namely, [Hg(N(1)-hexyl-5-flu...
