Crystalline structures of salts of oxalic acid and aliphatic amines
Journal Title: CHEMIK nauka-technika-rynek - Year 2014, Vol 68, Issue 4
Abstract
The article analyses crystalline structures of salts of oxalic acid and aliphatic amine. In such network there is multitude of arrangement forms for both mononegative and binegative oxalic acid anions. Mononegative anions might form cyclic dimers or arrange in linear chains of nature resembling stepwise structure, as well as in mixed chains. For binegative anions it is possible to distinguish linear flat chains and linear chains containing anions arranged perpendicularly to each other. In order to compare geometrical characteristics of hydrogen bonds of type O–H...O connecting mononegative ions in the crystal and in the „gas phase”, the quantum mechanical calculations were carried out using MP2 method.
