| Abstract: | The first tellurated derivative of morpholine, N-{2-(4-methoxyphenyltelluro)ethyl}morpholine (L1) has been synthesized by reacting in situ generated ArTe- with 4-(2-chloroethyl)morpholine hydrochloride under N2 atmosphere. The compound L1 gives
molecular ion peak at m:z 351 and is characterized structurally. The donor atoms N and Te in compound L1 are rightly oriented
for its ligation in bidentate mode. The Te-C(alkyl) is 0.02 A, longer than Te-C(aryl). The complexes of ligand L1 having composition [PtCl2(L1)2] (1) and [RuCl2(p-cymene)L1] (2) have been synthesized. The compound 1 has been characterized
structurally. The Pt has a square planar geometry in complex 1 and two molecules of ligand L1 bonded through Te alone are trans
to each other (Pt-Te-2.583(2) A, ). The 13C{1H} NMR spectrum of complex 1 is as expected. The 1H NMR spectrum of single
crystals of complex 1 shows multiplication of signals, which is supported by HETCOR experiments. The complex 2 also has ligand
L1 in a m... |
