Crystal structure of paddle-wheel sandwich-type [Cu(2){(CH(3))(2)CO}{μ-Fe(η(5)-C(5)H(4)C N)(2)}(3)](BF(4))(2)·(CH(3))(2)CO

The mol­ecular structure of (acetone-κO)tris­(μ-ferrocene-1,1′-dicarbo­nitrile-κ(2) N:N′)dicopper(I) bis­(tetra­fluorido­borate) acetone monosolvate, [Cu(2)Fe(3)(C(6)H(4)N)(6)(C(3)H(6)O)](BF(4))(2)·C(3)H(6)O, consists of two Cu(I) ions bridged by a ferrocene-1,1′-dicarbo­nitrile moiety in a paddle-wheel-architectured sandwich complex with two BF(4) (−) units as counter-ions. One of the latter is equally disordered over two sets of sites. The two Cu(I) ions are complexed in a trigonal–planar manner by three nitrile N-donor atoms. Further inter­actions by the O atom of an acetone mol­ecule to one of the Cu(I) atoms and a weak η(2),π-inter­action of two atoms of a cyclo­penta­dienyl ring to the other Cu(I) atom complete a distorted trigonal–pyramidal environment for each of the metal ions. A further acetone mol­ecule is also present as a solvent mol­ecule. The crystal packing is consolidated by several π–π inter­actions.
