摘要: The asymmetric unit of the title compound, [Zn2(C25H20N4)3](BF4)4·3CH3CN, consists one dinuclear ZnII complex cation with a triple-helical [Zn2L3]4+ motif (L is bis{4-[(pyridin-2-ylmethylidene)amino]phenyl}methane), four BF4− anions and three CH3CN solvent molecules. Zn⋯Zn separation 11.3893 (14) A ligands wrap around two atoms, forming triple helix as defined by Zn—N—N—Zn torsion angles 104.05 (18), 99.06 (19) 101.40 (19)°. Zn—N(pyridyl) distances in octahedral ZnN6 coordination sphere are range 2.128 (5)–2.190 (5) A Zn—N(imine) 2.157 (5)–2.277 (5) A.
