The reaction of cadmium nitrate dihydrate, propane-1,2-diamine and pyridine-2,6-dicarb-oxy-lic acid in a 1:1:2 molar ratio in an aqueous solution resulted in the formation of the title compound, (C(3)H(12)N(2))[Cd(C(7)H(3)NO(4))(2)]·2H(2)O or (p-1,2-daH(2))-[Cd(pydc)(2)]·2H(2)O (where p-1,2-da is propane-1,2-diamine and pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid). The Cd(II) ion is coordinate...

A new 2:1 co-crystal of piroxicam and gentisic acid [systematic name: 4-hy-droxy-1,1-dioxo-N-(pyridin-2-yl)-2H-1λ6,2-benzo-thia-zine-3-carboxamide-2-(4-oxido-1,1-dioxo-2H-1λ6,2-benzo-thia-zine-3-amido)-pyridin-1-ium-2,5-di-hydroxy-benzoic acid, 2C15H13N3O4S·C7H6O4] has been synthesized using a microfluidic platform and initially identified using Raman spectroscopy. In the co-crystal, one piroxi...

The existence of n-particle n-hole deformed yrare bands in the N=28 isotones is explored using full pf -shell diagonalizations and the Lanczos Strength Function method. We find different 2p-2h and 4p-4h collective bands that, when allowed to mix, more often disappear. Only the 2p-2h yrare band in Cr and the 4p-4h yrare band in Ni survive, and only in this latter case, due to the reduced density...

A combined matrix isolation FTIR and theoretical DFT/B3LYP/6-311++G(d,p) study of the molecular structure and photochemistry of 1-(tetrazol-5-yl)ethanol [1-TE] was performed. The potential energy surface landscapes of the 1H and 2H tautomers of the compound were investigated and the theoretical results were used to help characterize the conformational mixture existing in equilibrium in the gas ...

Target molecules based on Adamantane-pyrido[2,3-d]pyrimidine derivatives were prepared. series using N-(hydroxyadamantan-1-yl)-5-(2,4-substitutedphenyl)-2-Methyl-4-Oxo-7-(2-oxo-2H-Chromen-3-yl)pyrido[2,3-d]Pyrimidine-3(4H)carboxamide (6a-j) was synthesized by reaction between 3-(2-chloroacetyl)-5-(2,4-substitutedphenyl)-2-Methyl-7-(2-Oxo-2H-Chromen-3-yl) pyrido[2,3-d]pyrimidin-4(3H)-one (5a-j) ...

Several novel 6-thio-3-R-2-oxo-2H-[1,2,4]triazino[2,3-c]quinazoline-based compounds containing an ω-(dialkylamino(heterocyclyl)]alkyl fragment were synthesized to examine their anticancer activity. Some of the 6-{[ω-(hetero-cyclyl)alkyl]thio}-3-R-2H-[1,2,4]triazino[2,3-c]quinazoline-2-ones (3.1-3.10) were obtained by the nucleophilic substitution of 6-[ω-halogenalkyl]thio-3-R-2H-[1,2,4]triazino...

New coumarin derivatives, namely 7-[(5-amino-1,3,4-thiadiazol-2-yl)methoxy]-2H-chromen-2-one, 5-[(2-oxo-2H-chromen-7-yloxy)methyl]-1,3,4-thiadiazol-2(3H)-one, 2-[2-(2-oxo-2H-chromen-7-yloxy)acetyl]-N-phenylhydrazinecarbothioamide, 7-[(5-(phenylamino)-1,3,4-thiadiazol-2-yl)methoxy]-2H-chromen-2-one and 7-[(5-mercapto-4-phenyl-4H-1,2,4-triazol-3-yl)methoxy]-2H-chromen-2-one were prepared starting...
