SYNTHESIS AND STRUCTURE OF 1 1 COMPLEX OF ETHYLPHENYLTIN DICHLORIDE WITH N-4-METHOXYPHENYL-2-HYDROXYNAPHTHYLIDENEIMINE/

A novel organotin complex, EtPhSnCl(2) . 2HOC(10)H(6)CH = NC6H1OCH3 wa s synthesized, and its crystal structure was determined by X-ray diffr action method. The crystal is triclinic, belonging to space group, <P( 1)over bar> with unit cell parameters a = 1.150 8(5) nm, b = 1. 153 1( 5) gm, c = 1. 004 6 (3) nm, alpha = 94. 15 (3)degrees, beta = 115.47 ( 3)degrees, r = 85. 94 (4)degrees, V = 1199 7(1) nm(3), Z=2, D-c=1.68 g /cm(3), mu=13. 20 cm(-1), F(000)=618 for 4 131 reflections tions. R=0. 047, R(w)=0. 047. The ligand coordinates to tin atom via phenolic oxy gen atom. The complex has a distored trigonal bipyramidal structure, t he phenolic oxygen atom of the ligand and one of two chlorine atoms oc cupy the axial position. The distance between noncoodinated nitrogen a tom with phenolic oxygen atom is 0. 257 4 nm, which indicates that the intramolecular hydrogen bond of Schiff base ligand is retained in the complex.
