Layered (C5H6ON)2[Sb2O(C2O4)3] with a large birefringence derived from the uniform arrangement of π-conjugated units
An organic-inorganic hybrid antimony(III) oxalate (C5H6ON)2[Sb2O(C2O4)3] has been successfully obtained by simultaneous combination of π-conjugated 4-hydroxypyridine and (C2O4)2– group with stereochemical active Sb(III) cation. The compound features a layered structure, and the equatorial planes of SbO6 units, π-conjugated (C2O4)2– and (C5H6ON)+ groups are closer to a planar arrangement, representing strong structural anisotropy that favors a large birefringence. As expected, (C5H6ON)2[Sb2O(C2O4)3] exhibits a large birefringence of 0.279 at 546 nm. Structural and theoretical analyses indicate that the combination of multiple π-conjugated units is a feasible approach for designing and exploring new superior birefringent materials.
