Some new tin(IV) complexes with macrocyclic Schiff bases, viz. 1,5,9,13-tet
raaza-2,10-dimethyl-4,12-diphenyl cyclohexadeca-1,4,9,12-tetraene (L-1) and
1,4,8,12-tetraaza-6,9,13,14-dibenzocyclotetradeca-1,4,8,11-tetraene (L-2)
have been synthesized. An attempt has been made to probe their structures o
n the basis of elemental analyses, molecular weight determination, electron
ic, infrared, H-1. NMR and Sn-119 NMR spectroscopy. Molar conductance has s
hown the non-electrolytic behaviour of the tetravalent metal complexes that
appear to be 1 : 1 electrolytes. Six-coordinate structure has been propose
d for all tin complexes.
