A rare three-coordinated zinc coordination polymer based on 1,2,4-triazole and 5-tert-butylisophthalic acid: Synthesis, structure, and physical properties

ABSTRACT

A rare three-coordinated zinc coordination polymer [Zn₆(tbip)₄(trz)₂·H₂O]_n (1, Htrz = 1,2,4-triazole, H₂tbip = 5-tert-butylisophthalic acid) has been synthesized and characterized by IR spectra, elemental analysis, and single-crystal X-ray diffraction. The title complex features 3-D framework with (3,3,5)-connected (4.6.5)₂(4².6².8⁴.10²)(6².8) topology based on binuclear [Zn1(N)(COO)]₂ cluster motifs. The thermal stability and photoluminescence property of the title complex have been investigated.
