Presented here are two novel open-framework cobalt sulfate-oxalates constructed from molecular and chain-like building blocks. The two compounds have different structures: an hcb-type layer with 20-ring windows and a mog-type framework with 12-ring channels. Amine molecules play dual roles in the two structures: as a chelating ligand and a charge-balancing agent.

N,S-Dimethyldithiocarbamyl oxalates (e.g.6, 10) are novel, readily prepared precursors to alkyloxyacyl radicals 1 that are more suitable for kinetic studies than existing precursors; 10 has allowed the determination of accurate rate data for the cyclization of the butenyloxyacyl radical 5 (kc = 1.2 × 10(7) s(-1) at 21 °C).

A photovoltaic reactor was designed for artificial photosynthesis, based on the reactions involved in high energy hydrogen atoms, which were produced from water electrolysis. Water and CO2, under the conditions studied, were converted to oxalate (H2C2O4) and a polymer. This was the first time that the oxalates and oxalate-based polymer were produced from the artificial photosynthesis process.

Hyperoxaluria is a recognized cause of tubulointerstitial lesions, and this could contribute to development of hypertension and chronic renal failure. Enalapril has been effective against the progression of tubulointerstitial lesions in various animal models. The aim of the present study was to evaluate the usefulness of enalapril on the tubulointerstitial damage produced by oxalates. Two-month...

Two new metal phosphite-oxalates, CN3H6·Co(H2PO3)(C2O4) (1) and (CN3H6)2·Mn2.5(HPO3)(C2O4)2.5(H2O)·H2O (2), have been prepared under solvent-free conditions. The two open-framework compounds have diamondoid and pillared-layered structures, respectively. Their photoluminescence and magnetic properties were also investigated.

Because of the competition between the spin-orbit coupling and the Jahn-Teller (JT) energies in Fe(II)Fe(III) bimetallic oxalates, we theoretically predict that an undistorted phase with C3 symmetry about each Fe site may be recovered at low temperatures. Both lower and upper JT transitions bracketing the ferrimagnetic transition temperature Tc are predicted for compounds that exhibit magnetic ...
