A novel selenidostannate [V^II(dien)₂]₂[Sn₂Se₆] (1, dien = diethylenetriamine) was solvothermally synthesized and structurally characterized. 1 contains [V^II(dien)₂]²⁺ complex cations and dimeric [Sn₂Se₆]^4- anion based on two tetrahedral [SnSe₄] sharing a common edge, which provides the first example of the chalcogenidostannates directed by low-valent vanadium(II) complex as structure-directing agents (SDAs). 1 is a wide-band-gap semiconductor with absorption edge of 2.11 eV which shows photocurrent response properties. its magnetic properties and density functional theory calculation were also investigated.

一种新型硒代锡酸盐 [V ^II (dien) ₂ ] ₂ [Sn ₂ Se ₆ ] ( 1 , dien = 二亚乙基三胺) 被溶剂热合成和结构表征。1包含 [V ^II (dien) ₂ ] ²⁺复合阳离子和基于两个四面体 [SnSe ₄ ] 共享公共边缘的二聚体 [Sn ₂ Se ₆ ] ^4-阴离子，这是第一个由低-价钒 (II) 络合物作为结构导向剂 (SDA)。1是一种宽带隙半导体，吸收边为 2.11 eV，显示出光电流响应特性。还对其磁性和密度泛函理论计算进行了研究。
