Crystal Structure of Hydrochlorate of 1,1'-Bis[(4-pyridylamino)carbonyl]ferrocene

1 INTRODUCTION Recently, there is great current interest in the possibility of using organometallic complexes as ligands to construct mixed-metal suprastructures1], and ferrocenyl compounds containing mono-or poly- pyridyl fragments have also attracted much attention due to their strong coordinate abilities. For example, Grepioni and coworkers have described the design, synthesis and structure characterizations of several complexes Fe(η5-C5H4-1-C5H4N)2](AgI)22 /(CuII)24 / (ZnII)24…

Crystal Structure of Hydrochlorate of 1,1'-Bis[(4-pyridylamino) carbonyl] ferrocene

The hydrochlorate of 1,1'-bis(4-pyridylamino)carbonyl]ferrocene (C23H2303N4ClFe,Mr = 494.75) was structurally characterized by means of X-ray single-crystal diffraction. It crystallizes in triclinic, space group Pī with a = 9.5299(19), b = 12.792(3), c = 9.2644(19)(。A), α =91.56(3), β = 101.97(3), γ= 74.71(3)°, V = 1065.2(4)(。A)3, Z = 2, Dc = 1.542 g/cm3, F(000) = 512,μ(MoKα) = 0.868 mm 1, T = 291(2) K, the final R = 0.0596 and wR = 0.1531 for 2842 observed reflections with I ＞ 2σ(I). Interestingly, two 1,1'-bis(4-pyridylamino)carbonyl]ferrocenes (4-BPFA)join shoulder-to-shoulder through intermolecular hydrogen bonds N-H……N, forming an unexpected macrocycle with dimensions of 3.385(。A) × 15.778(。A).
