C-methyl resorcinarene bis-crown-5 (1) with pendant methyl groups at the lower rim was
prepared and crystallized in various solvent mixtures with and without selected metal salts.
The crystal structures of two polymorphic forms of unsolvated 1 (1-I and 1-II), three solvates
(acetonitrile, chloroform and dichloromethane-methanol), and three metal complexes with
silver and cesium salts were obtained. The lower rim methyl groups and the block shape of the
host promote crystal packing in brick-wall type assemblies, in which the binding cavities are
efficiently filled by the crown bridges. Thus, solvents are found in the interstitial space or
coordinated to the crown bridges on top of the cavity, whereas more strongly binding metal
cations are able to occupy the cavity. The chloroform solvate proved to be a relatively labile
crystal form, which transformed to unsolvated form (1-I) over time. Resorcinarene monocrown-5
(2) was obtained as a minor product of the bridging reaction. Two solvate structures
(acetonitrile and chloroform-water) of 2 are also reported, providing an example of the effect
of the missing crown bridge on the solvate structures.

A cocrystal of two Mo(VI) complexes bearing different diastereomers of the 2,4-di-tert-butyl-6-{[(1-oxido-1-phenylpropan-2-yl)(methyl)amino]methyl}phenolate ligand derived from (+)-ephedrine
Sillanpää, Reijo; Hänninen, Mikko M. (Wiley-Blackwell, 2013)The title cocrystal contains two chiral conformational diastereomers, viz. (1S,2R,RN)- and (1S,2R,SN)-, of [2,4-ditert-butyl-6-{[(1-oxido-1-phenylpropan-2-yl)(methyl)amino]- methyl}phenolato](methanol)-cis-dioxidomolyb ... -
Synthesis and characterization of ferrocene-based Schiff base and ferrocenecarboxaldehyde oxime and their adsorptive removal of methyl blue from aqueous solution
Lasri, Jamal; Elsherbiny, Abeer S.; Eltayeb, Naser Eltaher; Haukka, Matti; El-Hefnawy, Mohamed E. (Elsevier BV, 2018)The ferrocene-based Schiff base 3 was synthetized by reaction of ferrocenecarboxaldehyde 1 with 4-aminoantipyrine 2. However, the reaction of 1 with hydroxylamine affords ferrocenecarboxaldehyde oxime 4. Compounds 3 and 4 ... -
