Tridentate Schiff Base

The title complex was isolated as a red solid from the reaction of 4-(salicylaldiminato)antipyrine, HL, and cobalt (II) acetate in ethanol. The complex has been characterized by elemental analysis, FTIR, UV-Vis, and X-ray single crystal diffraction. Two crystallographically different cationic units, A and B, of the title complex are found. Both units are essentially isostructural; nevertheless, small differences exist between them. Both units contain four cobalt atoms arranged at the corners of distorted cubane-like core alternatively with phenoxy oxygen of the Schiff base. In both cases, one cobalt binds to three coordinated sites from the corresponding tridentate Schiff base ligand, and the fourth one was bonded by the acetate oxygen, and the fifth and the sixth donor sites come from the phenolate oxygen of another Schiff base ligand.

Three diorganotin(IV) chelates with a tetradentate Schiff base, H2Vanophen, [H2Vanophen = N,N′-1,2-phenylen-bis(3-methoxysalicylideneimine)] of the type R2Sn(Vanophen) (R = Ph: 1; R = n-Bu: 2; R = Me: 3) have been synthesized by the reaction of R2SnCl2 (R = Ph, n-Bu, Me) and H2 Vanophen in the presence of triethylamine in benzene. The complexes have been characterised by IR and NMR spectroscopy and by elemental analysis. The δ(119Sn) values for the complexes 1 - 3 are -543.0, -414.2 and -398.2 ppm respectively, indicating hexacoordinated Sn centers. These have been ascertained by X-ray crystal structure determinations of 1 and 3. The distances between tin and the two axial carbon atoms in each complex differ not significantly [2.17(1) Å in 1, and 2.100(3) and 2.115(3) Å in 3). The C-Sn-C angles for 1 and 3 are 165.9(4)° and 159.96(9)°, respectively. The solution NMR spectra (1H , 13C, 119Sn) show clearly that the solid state structures are retained in solution.
