Synthesis and crystal structures of two solvates of 1-{[2,6-bis­(hy­droxy­meth­yl)-4-methyl­phen­oxy]meth­yl}-3,5-bis­{[(4,6-di­methyl­pyridin-2-yl)amino]meth­yl}-2,4,6-tri­ethyl­benzene

In the crystal structures of the formamide monosolvate (1a) and the n-propanol/H(2)O solvate/hydrate (1b) of the title compound, C(38)H(50)N(4)O(3) (1), the tripodal host mol­ecule 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 supra­molecular architecture, while the crystal structure of 1b consists of two-dimensional supra­molecular aggregates extending parallel to the crystallographic ab plane.
