Crystal Structure And Luminescent Property of a New Two-Dimensional Polymer Based on 1,4-Bis(4-(Imidazole-1-yl)Benzyl)Piperazine

Abstract

A two-dimensional Zn(II) complex [Zn(BIBP)(TBIP)]_n (1) (BIBP = 1,4-bis(4-(imidazole-1-yl)benzyl)piperazine, H₂TBIP = 5-tert-butyl isophthalic acid) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. The single crystal X-ray diffraction analysis reveals that complex 1 is an achiral two-dimensional layer based on 1D left- and right-handed helical [Zn(BIBP)]_n² chains, which are linked by C—H⋯O hydrogen bonds to form a three-dimensional supramolecular framework. Moreover, complex 1 exhibits an emission band at 393 nm (λ_ex = 244 nm).
