A novel 3-D chiral bismuth–organic framework with mixed carboxylate, pyridine and thiolate donors exhibiting a semiconductive property

Abstract

A novel 3D bismuth–organic framework with helical channels, {[Bi(mna)₂]⁻·(HDMA)⁺}_n (1, H₂mna = 2-mercaptonicotinic acid, DMA = dimethylamine) based on homo-chiral Bi–mna helices was hydrothermally synthesized and characterized. The optical diffuse reflectance spectrum and the theoretical calculations indicate that compound 1 is a potentially semiconductive material.
