The reaction of [Ti]Cl 2 ( 1) {[Ti](η 5-C 5H 4SiMe 3) 2Ti} with two equivalents of LiCC–SiMe 2–CCSiMe 3 ( 2) produces [Ti](CC–SiMe 2–CCSiMe 3) 2 ( 3). On treatment with [MX] (M=Cu: 4a X=Cl, 4b X=Br; M=Ag: 5a X=Cl, 5b X=Br) the tweezer complexes {[Ti](CC–SiMe 2–CCSiMe 3) 2}MX (M=Cu: 6a X=Cl, 6b X=Br; M=Ag: 7a X=Cl, 7b X=Br) are formed in which the Ti–CC–Si units are η 2-coordinated to a monomeric copper(I) or silver(I) halide moiety. When 6b is further reacted with [CuBr] ( 4b), oligomeric {[Ti](CC–SiMe 2–CCSiMe 3) 2(CuBr) 3} n ( 8) is formed. This molecule contains a (η 2-TiCCSi) 2CuBr entity next to two (η 2-SiCCSi)CuBr moieties, of which the latter building blocks are responsible for the oligomeric structure. In addition, 8 can be prepared by the direct reaction of 3 with an excess of 4b, respectively. However, when an excess of [AgX] is used, the only formed products are 7; no polymeric material is obtained. A Group 11 metal exchange reaction is noticed, when 7a or 7b are reacted with [CuX]: depending on the amount of [CuX] used, monomeric 6 or oligomeric 8 is produced. An explanation is given by a better bonding synergysmus for the alkyne-to-copper interaction. The result of the X-ray structure analysis of compound 7b is reported. The compound 7b crystallizes in the monoclinic space group C2/ c with cell constants a=25.097(8), b=11.327(3), c=19.014(6) Å, β=122.36(3)°, V=4566(2) Å 3 and Z=4. The compound 7b contains a monomeric (η 2-alkyne) 2AgBr moiety in which the silver(I) center possesses a trigonal-planar environment, caused by the η 2-coordinated TiCCSi units as well as a η 1-bonded bromine atom. However this differs from the behavior of compounds 6 and 7 in solution, where all four CC building blocks of the TiCCSi as well as the SiCCSi units are complexed by the transition metal entities MX (M=Cu, Ag X=Cl, Br).
