摘要：
The asymmetric unit of the title compound, [Zn-2(C25H20N4)(3)](BF4)(4)center dot 3CH(3)CN, consists of one dinuclear ZnIT complex cation with a triple-helical [Zn2L3](4+) motif (L is bis{4-[(pyridin-2-ylmethylidene)amino]phenyllmethane), four BF4- anions and three CH3CN solvent molecules. The Zn center dot center dot center dot Zn separation is 11.3893 (14) angstrom 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)degrees. The Zn N(pyridyl) distances in the octahedral ZnN6 coordination sphere are in the range 2.128 (5)-2.190 (5) angstrom and the Zn N(imine) distances are in the range 2.157 (5)-2.277 (5) angstrom.
