SYNTHESIS AND CHARACTERIZATION OF POLYMERIC AG(I)-TELLUROETHER AND CU(I)-DIORGANYL DITELLURIDE COMPLEXES - CRYSTAL-STRUCTURES OF [AG(METE(CH2)(3)TEME)(2)](N)[BF4](N), [(MU(2)-METETEME)CU(MU-CL)](N), AND CCH3)(4)(MU(2)-(P-C6H4F)TETE(P-C6H4F))(2)][BF4](2)

Reaction of ligand MeTe(CH2)(3)TeMe with AgBP4 in CH3CN produced the l ight-sensitive polymeric coordination complex [Ag(MeTe(CH2)(3)TeMe)(2) ](n)[BF4](n). This compound crystallized in the monoclinic space group P2(1)/n with 8.755(3) Angstrom, b = 20.441(8) Angstrom, c = 12.227(3) Angstrom, beta = 103.13(3)degrees, V = 2130.9(12) Angstrom(3), Z = 4, F(000) = 1504. Final R = 0.057 and R(w) = 0.062 resulted from refinem ent of 2776 total reflections with 154 parameters. Reaction of (Te(p-C 6H4F))2 and AgBF4 in acetonitrile at ambient temperature generated red , light-sensitive CH3)(4)(mu(2)-(p-C6H4F)TeTe(p-C6H4F))(2)][F-4](2), a homodiorganyl ditelluride doubly-bridged complex. Crystal data: tricl inic space group P (1) over bar, a = 6.835(2) Angstrom, b = 13.255(2) Angstrom, c = 13.824(4) Angstrom, alpha = 116;48(3)degrees, beta = 95. 95(2)degrees, gamma = 98.90(2)degrees, V = 1086.2(4) Angstrom(3), Z = 1, rho(calcd) = 2.165 g cm(-3), mu = 36.13 cm(-1), F(000) = 668. Refin ement of 3807 reflections and 254 parameters gave R = 0.027 and R(w) = 0.028. Treatment of (MeTe)(2) with CuCl in CH3CN at ambient temperatu re yielded polymeric [(mu(2)-MeTeTeMe)Cu(mu-Cl)](n). Crystal data: mon oclinic space group P2(1)/ c, a = 9.923(2) Angstrom, b = 8.091(2) Angs trom, c = 10.232(3) Angstrom, beta = 116.01(2)degrees, V = 738,3(3) An gstrom(3), Z = 2, F(000)= 668. Refinement of 949 reflections and 56 pa rameters gave R = 0.027 and R(w) = 0.025.
