Figure 3
(a) Water and DMSO mol­ecules fitting the voids formed by the packing of two [Er(Htmpa)4(H2O)] com­plexes. [Symmetry code: (vi) −x + 1, −y + 2, −z.] Displacement ellipsoids are drawn at the 50% probability level and molecules inside the voids as a ball-and-stick model. Orange dotted lines represent hydrogen bonds. H atoms have been omitted for clarity. (b) Inter­action of the [Er(tmpa)4(H2O)] com­plex with the mol­ecules of crystallization. Er, C, O, N and S atoms are coloured in green, gray, red, blue and yellow, respectively. Displacement ellipsoids are drawn at the 50% probability level. (c) Perspective drawing of two anionic entities of inclusion com­plex 1 (omitting the H atoms), in which the space-filling model represents the DMSO and H2O solvent mol­ecules.
