摘要：

Reported here are two solvothermally synthesized metal selenides, namely [Cu2MSe5][Mn(H+-en)(2)(en)] (M=Ge (1) and Sn (2), and en=ethanediamine). The two isostructural compounds feature a 1-D anionic chain of [Cu2MSe5](4-) with the existence of strong Cu center dot center dot center dot Cu interaction. The estimated optical band gap was determined to be 1.69 eV for 1 and 1.49 eV for 2, indicating their semiconducting nature. Interestingly, 2 exhibits NIR-triggered photoelectric response, which make it potential semiconductor sensor used in photoelectric devices.
