Thirty complexes of the type [SnX2.L1‒10] (where X = Cl or Br or CH3COO and L1‒10 = macrocyclic ligands) have been synthsised and characterized by elemental analysis, molar conductance, IR and XPs data. A distorted octahedral geometry was also established. In the continuation of synthesis of [SnX2.L1‒10] complexes (Where X = Cl or Br or CH3COO and L1‒10 = macrocyclic ligands derived from condensation of trimestic acid i.e. Benzene 1,3,5–tricaboxylic acid and various diamines) [1]; in this research paper synthesis and characterisation of [SnX2.L1‒10] molecular adducts (where X = Cl or Br or CH3COO and L1‒10 = macrocyclic Saciff base ligands) L1 to L10 derived from condensation of p–thathalic acid i.e. terephthalic acid with different diamines i.e. in L1= NH2CH2CH2CH2NH2; in L2=NH2CH2CH(CH3)CH2NH2; in L3=NH2CH2NH(CH2)2NH2; in L4=NH2CH2C(CH3)2CH2NH2; in L5=NH2(CH2)6NH2; in L6=NH2(CH2)7NH2; in L7=NH2(CH2)8NH2; in L8=NH2(CH2)9NH2; in L9=NH2(CH2)10NH2; and L10=NH2(CH2)12NH2; will be perform and their structure and geometry will be propose on basis of physicochemical methods.

Elemental analysis, molar conductivity, macrocyclic schiff base ligand, molar conductivity, X-ray and IR photoelectron spectra.
