Syntheses, Structures, and Photophysical Properties of Two Coordination Polymers Based on 2,3‐Dioxo‐1,2,3,4‐tetrahydroquinoxaline‐6‐carboxylic Acid

Abstract

Two complexes based on the ligand 1,4-dihydro-2,3-quinoxalinedione, namely [Mn(H 2 L) 2 (H 2 O) 2 ] n (1) and {[Zn 2 (H 2 L) 2 (tz) 2 ]·5H 2 O} n (2) (H 3 L = 2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylic acid, Htz = 1,2,4-triazole) were hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, as well as single-crystal and powder X-ray diffraction. Complex 1 exhibited a 1D comb-like chain formed by H 2 Lanions linking Mn II ions, whereas
