•Compound 1 displays a novel chiral highly connected structure.•Compound 1 is characterized by single-crystal X-ray diffraction analysis, EA, IR and UV–Vis spectra.•Compound 1 is a potential semiconductor with wide band gap.•The photoluminescent spectrum of compound 1 has been studied.

A novel coordination polymer, namely, [Cd7(4,4′-tmbpt)3(d-cam)6(OH)2]·8.25H2O (1), where 4,4′-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3,5-bis(4-pyridyl)-1,2,4-triazole, and d-H2cam = d-camphoric acid, has been synthesized under hydrothermal condition. Compound 1 exhibits a three-dimensional homochiral (3,8,9)-connected framework, which is a rare example of coordination polymer with homochiral highly connected structure based on the chiral source of d-H2cam. The structure of the compound was determined by single-crystal X-ray diffraction analysis and further characterized by infrared spectrum (IR), elemental analysis and UV–Vis spectrum. Moreover, the optical band gap and photoluminescent property of the compound have been investigated.
