Synthesis and crystal structures of two solvates of 1-{[2,6-bis-(hy-droxy-meth-yl)-4-methyl-phen-oxy]meth-yl}-3,5-bis-{[(4,6-di-methyl-pyridin-2-yl)amino]meth-yl}-2,4,6-tri-ethyl-benzene

Abstract

In the crystal structures of the formamide monosolvate (1a) and the n-propanol/H₂O solvate/hydrate (1b) of the title compound, C₃₈H₅₀N₄O₃ (1), the tripodal host mol-ecule adopts a conformation in which the substituents attached to the central benzene ring are arranged in an alternating order above and below the ring plane. As a result of the different nature of the involved guest species, the crystal components in 1a create a three-dimensional supra-molecular architecture, while the crystal structure of 1b consists of two-dimensional supra-molecular aggregates extending parallel to the crystallographic ab plane.

Keywords: C—H⋯π and π–π inter­actions; crystal structures; hydrogen bonding; tripodal mol­ecule.
