Powder diffraction investigations of 2,2′-thiobis(4-methyl-6-tert-butylphenol) and 2,2′-methylenebis(4-methyl-6-tert-butylphenol)

X-ray diffraction investigations of two phenol derivatives - 2,2 '-Thiobis(4-methyl-6-tert-butylphenol) and 2,2 '-Methylenebis(4-methyl-6-tert-butylphenol) were carried out. Both compounds at room temperature have similar cell volume and the same number of molecules in an unit cell. However, 2,2 '-Thiobis(4-methyl-6-tert-butylphenol) crystallizes in the monoclinic system with unit cell parameters refined to a = 0.8278(2) nm, b = 1.2968(4) nm, c = 1.9493(7) nm, beta = 90.93(2)degrees, space group P2(1)/n(14), whereas 2, 2 '-Methylenebis(4-methyl-6-tert-butylphenol) crystallizes in the orthorhombic system with unit cell parameters refined to a = 1.6203(5) nm, b = 1.2827(5) nm, c = 1.0197(3) nm, space group Pna2(1)(33). The investigated C22H30O2S turned out to be a new polymorph of 2, 2 '-Thiobis(4-methyl-6-tert-butylphenol). (c) 2005 International Centre for Diffraction Data.
