[AEPH2][GeSb2S6]·CH3OH: a thiogermanate–thioantimonate featuring an infinite ribbon-like structure with an unusual {GeSb3S11} unit and exhibiting the ability of photocatalytic degradation of organic dye

A new thiogermanate–thioantimonate, namely, [AEPH2][GeSb2S6]·CH3OH (1) (AEP = N-(2-aminoethyl)piperazine) has been solvothermally synthesized, whose structure features a one-dimensional anionic ribbon of [GeSb2S6]n2n− built of the firstly observed tetranuclear {GeSb3S11} cluster as secondary building unit. The photocatalytic study indicated that 1 was able to degrade Rhodamine B under visible irradiation. [ABSTRACT FROM AUTHOR]
