摘要

A redox, substitution and self-assembly reaction offers a novel dysprosium selenoarsenate(III) with As3+ [Dy-2(tepa)(2)(mu(2)-OH)(2)Cl-2](3)[As3Se6](2) (1, tepa = tetraethylenepentamine), which provides the first example of chair conformation ring [As3Se6](3-) combined with lanthanide complexes as counterions. 1 exhibits a photocurrent response and slow magnetic relaxation behavior.
