Abstract: | Abstract As intermediates of light stabilizer malonate, diethyl 3,5-di-t-butyl-4-hydroxybenzyl phenyl malonates (F.W. 454.58) was synthesized,
characterized by 1H NMR, element analysis and confirmed by X-ray crystal structure analysis. This compound crystallizes in monoclinic class
under the space group P21/c with cell parameters, a = 9.8218(4) ?, b = 13.5571(5) ?, c = 19.7233(8) ?; β = 102.3530(10)°,
and Z = 4. The structure exhibits inter-molecular hydrogen bonds of the type O–H–O, leading to the formation of one dimensional
chains. |
