Crystal structure of tris­(μ-bis­{4-[(pyridin-2-yl­methyl­idene)amino]­phen­yl}methane-κ(4) N,N′:N′′,N′′′)dizinc tetra­kis­(tetra­fluorido­borate) aceto­nitrile tris­olvate

The asymmetric unit of the title compound, [Zn(2)(C(25)H(20)N(4))(3)](BF(4))(4)·3CH(3)CN, consists of one dinuclear Zn(II) complex cation with a triple-helical [Zn(2) L (3)](4+) motif (L is bis­{4-[(pyridin-2-yl­methyl­idene)amino]­phen­yl}methane), four BF(4) (−) anions and three CH(3)CN solvent mol­ecules. The Zn⋯Zn separation is 11.3893 (14) Å and the ligands wrap around the two Zn(II) atoms, forming a triple helix as defined by the Zn—N—N—Zn torsion angles of 104.05 (18), 99.06 (19) and 101.40 (19)°. The Zn—N(pyrid­yl) distances in the octahedral ZnN(6) coordination sphere are in the range 2.128 (5)–2.190 (5) Å and the Zn—N(imine) distances are in the range 2.157 (5)–2.277 (5) Å.
