Bis­[bis(N,N‐diethyl‐1,1‐di­seleno­car­bam­ato)copper(II)], [Cu(Se2CNEt2)2]2

The title centrosymmetric Cu^II binuclear complex, bis(μ‐N,N‐diethyl‐1,1‐di­seleno­carbamato‐Se,Se′:Se)­bis­(N,N‐diethyl‐1,1‐di­seleno­carbamato‐Se,Se′)copper(II)], Cu(Se₂CNEt₂)₂]₂ or Cu₂(C₅H₁₀NSe₂)₄], is built from two symmetry‐related Cu{Se₂CN(Et)₂}₂] units by pairs of Cu—Se bonds. The coordination geometry at the unique Cu atom is distorted square pyramidal, with Cu—Se distances in the range 2.4091 (11)—2.9095 (10) Å.
