Abstract
The crystal structure of new racemic di-Mannich base 2,2′-(3aR,7aR/3aS,7aS)-hexahydro-1H-benzo[d]imidazole-1,3(2H)-diyl)bis(methylene)bis(4-methylphenol) (4), is reported. The structure of the title compound, C23H30N2O2, shows two intramolecular O–H···N hydrogen bonding interactions. This compound crystallizes in triclinic symmetry, in space group P−1, with lattice constants: a = 6.2563(3) Å, b = 12.1743(7) Å, c = 14.7257(7) Å, α = 108.11(1)°, β = 99.77(1)°, γ = 98.78(1), V = 1024.97(9) Å3, Z = 2, F(000) = 396, R 1 = 8.3%, wR 2 = 14.7%.
