Two new copper bromide based coordination compounds 0D-Cu2Br2 (3,5-dimethyl-pyridine)(4) (1) and 1D-Cu2Br2(5-bromo-pyrimidine)(2) (2) have been synthesized and structurally characterized. X-ray diffraction analyses reveal that the inorganic module of both compounds is Cu2Br2 rhomboid dimer coordinated by the organic ligands. Compound 1 is a zero-dimensional (0D) molecular complex while compound 2 is one-dimensional (1D) extended structure. Photoluminescence measurement results show that 1 emits green photoluminescence peaked at 520 nm, with an IQY of 82.4%. Compound 2 emits red photoluminescence peaked at 630 nm, with an IQY of 2.1%. Both compounds exhibit potential as rare-earth metal free lighting phosphor alternatives.
