Abstract: | Abstract The synthesis and X-ray crystal structure of 2,4,6-trimethyl-1,3,5-tris(4-oxymethyl-1-formylphenyl)benzene (2) and the crystal structure of its core molecule, 1,3,5-tris(bromomethyl)-2,4,6-trimethylbenzene (1) are reported. The compounds 1 and 2 crystallize in the triclinic system with space group P ī. The lattice parameters of 1 and 2 are a = 9.454(2) ?, b = 9.478(4) ?, c = 9.573(2) ?, α = 116.53(2)°, β = 109.705(14)°, γ = 101.293(18)°, V = 658.5(4) and a = 15.7707(6) ?, b = 16.3646(5) ?, c = 18.2805(6) ?, α = 83.202(2)°, β = 66.0120(10)°, γ = 73.704(2)°, V = 4137.2(2), respectively. In the crystals of 1 and 2, there are one and three molecules in the asymmetric unit, respectively. The packing of the molecules in the solid is stabilized
through van der Waals interactions in 1 and weak C–H···O and C–H···π interactions in 2. |
