Optical waveguide materials are widely used in optical conversion and communication systems, but their harsh preparation conditions limit practical applications. Herein, we present two zero-dimensional organic metal halide hybrids (OMHHs) with excellent properties, which formed by cocrystallization of d10 transition zinc 2,5-bis(4-pyridinium)thiazolo[5,4-d]thiazole (TTz) using a simple solution-based method. Both compounds have the loss coefficient R for (H2TTz)ZnCl4·MeOH (1) being 0.01577 dB·μm–1 at 462 nm (H2TTz)·ZnBr4·MeOH (2) 0.01182 515 nm, respectively. Our work reveals great potential OMHH microcrystals photonic technology also provides new enlightenment application low-loss waveguides.
