A New Study On Transition Metal Derivatives Of Ferrocene Pt-II

P.P.Singh, V.B.L.Srivastava, Deepa Singh

Ferrocene on reaction with HgXCN [X= S, Se] forms 1,1′bis (thiocyanato/ selenocyanato) ferrocene. This compound acts as bidendate ligand and forms an adduct with M(NCS)2 [M= Fe(II), Co(II), Ni(II), Cu(II), Zn(II)]. The bond length, bond order and bond angle of the ligands and the adducts have been evaluated with the help of Cache software. The bond length and bond angle indicate that basic structure of ferrocene is not altered after the formation of ligand or the adducts. The bidenlate nature of 1,1′bis( thiocyanato/selenocyanato) ferrocene is supported by the bond angles. The bond angles around M in various compounds is either 113 degree or 180 degree, which shows that M is well exposed for further reaction. The length of M-NCS bond changes on change of M which is the following order Zn > Cu > Ni > Fe > Co. This change has been attributed to the difference in the nature of sd hybridization.
