RETRACTED ARTICLE: Auxiliary ligand directed two new Zn(II) compounds: from 2D→3D polythreaded framework to 2-fold interpenetrated 3D framework.

AbstractTwo new Zn(II) compounds, namely [Zn(tdc)(biimpy)]n·<italic>x</italic>(solvent) (1) and {[NH2(CH3)2]2[Zn2(tdc)3(DABCO)]}n (2) (H2tdc = 2,5-thiophenedicarboxylic acid, biimpy = 2,6-bis(1-imidazolyl)pyridine, DABCO = 1,4-diazabicyclo[2.2.2]octane), were successfully synthesized <italic>via</italic> the solvothermal reactions of H2tdc and Zn(NO3)2 together with biimpy or DABCO as the auxiliary ligand. Single crystal X-ray structural analyses revealed that compound <bold>1</bold> features a 2 D layered structure with 3-connected <bold>hcb</bold> topology and these 2 D layers are further packed into a 3 D supramolecular framework with 2 D→3D polythreaded motifs directed by intermolecular π…π interactions, and compound <bold>2</bold> features a 2-fold interpenetrated 3 D framework with <bold>lon</bold> topology. Moreover, the thermal stabilities and luminescent properties of these two compounds were also investigated. [ABSTRACT FROM AUTHOR]
