A new tripodal ligand containing ferrocenyl and hydrazone groups was synthesized by the condensation of ferrocenylcarbonylhydrazine with tris {[2 (2 formylphenyl)oxo]ethyl}amine and characterized by elemental analyses, IR and 1H NMR. It is expected to be an important ligand to react with transition metals to give functional coordination complexes with interesting physical chemical properties. Studies on its reactions and properties are in progress.
Complex [Ag 2(DPYBIM)(dppm)](BF 4) 2·CH 3OH was obtained from the reaction of AgBF 4 and the hetero-armed tripodal ligand DPYBIM [N,N-bis(2-pyridylmethyl)-N-(2-benzimidazolylmethyl)amine] with the participation of dppm [bis(diphenylphosphino)- methane]. Single crystal X-ray diffraction analysis showed that the crystal belongs to the triclinic space group P1-. The cell parameters are: M r=1135.17, a=1.0619(2) nm, b=1.4246(3) nm, c=1.6767(3) nm, α=91.08(3)°, β=104.04(3)°, γ=101.77(3)°, V=2.4027(8) nm 3, D c=1.569 Mg/m 3, Z=2, F(000)=1140, μ=9.53 cm -1, R=0.057, wR=0.145. In the complex, one of the Ag atoms is linearly coordinated by PN from dppm and the benzimidazolyl group of the tripodal ligand, respectively, while the other is tetrahedrally coordinated by PN 3 where two of the N atoms are from the pyridine arms and one is the amino-N. Two types of intermolecular π...π interactions lead to the 1D infinite "Z"-shaped chain. The complex was characterized by elemental analysis, IR and MS. 31P NMR showed characteristic AA′XX′pattern of two symmetrical multiplets centered at δ=10.07.
