Ninety Cr(III) macrocyclic Schiff base complexes of the type [CrL_n^(1-10) X_2 ]X(Where X = Cl- or NO-3 or CH3COO- and = macrocyclic Schiff base ligands derived from condensation of trimesic acid or p-phthalic acid or squaric acid with different aliphatic diamines) have been synthesised and characterised by elemental analysis; molar conductance; electronic spectra; IR; magnetic moment and XPS i.e. X-ray Photoelectron spectra data. An octahedral geometry was established for them.

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.

Two new manganese(III) Schiff base complexes,  [Mn(salen)(m-NO2-C6H4CO2)(H2O)] (1) and  [Mn(msalen) (p-OH-C6H4CO2)(H2O)] (2), where H2salen = N,N'-bis(salicylidene)-1,2-diaminoethane, H2msalen = N,N'-bis (3-methoxysalicylidene)-1,2-diaminoethane were synthesized from the manganese (II) carboxylates.  Single crystal X-ray diffraction studies show that the Jahn-Teller distorted octahedral complexes are stabilized by              H-bonded chains and networks in the solid state.

During the syntheses of the Schiff base 2-methoxy-6-{[(tiophen-2-methyl)imino]methylphenol (o-HVATPNH2), a co-´product was isolated and characterized. The crystal structure of this molecule, 4,10-dimethoxy-13-(thiophen-2-ylmethyl)-6,12-dihydro-6,12-epiminodibenzo[b,f][1,5]dioxocane, namely (o-VA)2TPNH2 for short, was determined by X-ray...
