Abstract

Two organic hybrid manganese selenoarsenates, [Mn(en)₃][MnAs^II₂Se₄] (1; en = ethanediamine) and {[Mn(atep)]₂[Mn(tepa)](As^VSe₄)₂} [2; atep = 4-(2-aminoethyl)triethylenetetramine], were made under mild solvothermal conditions. 1 is a new type of one-dimensional low-valent selenoarsenate(II) constructed by the linkages of tetrahedral [MnSe₄] units and two manners of bridging of [As^II₂Se₄]^4- anions. 2 comprises a neutral {[Mn(atep)]₂[Mn(tepa)](As^VSe₄)₂} molecule with a rare seven-coordinated manganese center, which represents the sole example of an organic hybrid selenoarsenate with the [Mn(tepa)]²⁺ complex as the bridging group. Both 1 and 2 exhibit special photocurrent responses upon visible-light illumination and magnetic properties.
