  Ditelluroether ligand bis(4-methoxyphenyltelluro)methane — synthesis, reaction with iodine and its ruthenium(II) complexes. Crystal structures of (4-MeOC6H4Te)2CH2, {4-MeO-C6H4Te(I2)}2CH2 cis-[Ru(DMSO)2Cl2(4-MeOC6H4Te)2CH2] and [(p-cymene)Cl2Ru(μ-{(4-MeOC6H4Te)2CH2})RuCl2(p-cymene)]

  摘要：

  The reaction of chloroform with ArTe- Na+ (Ar = 4-MeOC6H4), generated in situ by borohydride reduction of Ar2Te2, results in a high purity sample of bis(4-methoxyphenyltelluro)methane (1) (yield similar to 90%). Its single crystal structure has been reported. The Te-C-Te angle is found to be 117(1)degrees. The oxidative addition of I-2 to 1 results in {4-MeO-C6H4Te(I-2)}(2)CH2 (1a), which is also characterized structurally. The iodine atoms at each Te atom occupy axial positions. The two Te-I bonds are longer than the other two. The intermolecular contacts of I(2) and I(4) with the neighbouring Te atoms lead to polymeric links of essentially Te-I-Te'-I' rectangular bridges tangles 89.07(3)-94.68(3)degrees. The complexes of 1 with Ru(II) viz. cis-[Ru(DMSO)(2)Cl-2(4-MeOC6H4Te)(2)CH2] (2) and [(p-cymene)Cl2Ru(mu-1)RuCl2(p -cymene)] (2a) are synthesized and characterized structurally. The geometry of Ru(II) in the complex 2 is distorted octahedral. (Ru-Te 2.598815)-2.6727(5) Angstrom; Te(1)-Ru(1)-Te(2)= 78.2(2)degrees; Te(1)-Ru(1)-Cl(2)= 76.6(2)degrees. The distortions are not shared equally by the two tellurium atoms. The Te(1) displays much larger distortions of cis angles than those involving Te(2). The Te-C(aromatic) distances are shorter than Te-C(alkyl) bond lengths. The 2a is the first example in which the ligand 1 is shown to coordinate in a bridging mode, i.e. with two Ru atoms (Ru-Te 2.6381(16)-2.5411(2) Angstrom). The Te(1)-C-Te(2) angle is 119.3(9)degrees. Similarly 2 is also the first example that has four membered chelate ring containing Ru and two Te atoms. (C) 2000 Elsevier Science S.A. All rights reserved.

  A novel and convenient route for the synthesis of bis(4-methoxyphenyltellro)methane using one pot reaction of ditelluride, sodium borohydride and chloroform is described. The palladium(II) complexes of this ditelluroether ligand were also synthesized. The structure of the palladium(II) complex was confirmed by X-ray diffraction studies. The red complex [Pd(4-CH3OC6H4Te)2CH2}Cl2] crystallizes in monoclinic
