ZINCSELENIDE AND ZINCTELLURIDE CLUSTERS WITH PHENYLSELENOLATE AND PHENYLTELLUROLATE LIGANDS - THE CRYSTAL-STRUCTURES OF [NET4](2)[ZN4CL4(SEPH)(6)], [NET4](2)[ZN8CL4SE(SEPH)(12)], [ZN8SE(SEPH)(14)(PNPR(3))(2)],[(HPPR2R)-PR-N](2)[ZN8CL4TE(TEPH)(12)] (R = PR-N, PH), AND [ZN10TE4(TEPH)(12)(PR3)(2)] (R = PR-N, PH)

In the prescence of NEt4Cl ZnCl2 reacts with PhSeSiMe3 or a mixture of PhSeSiMe3/Se(SiMe3)(2) to form the ionic complexes [NEt4](2)[Zn4Cl4(S ePh)(6)] 1 Or [NEt4](2)[Zn8Cl4Se(SePh)(12)] 2 respectively. The use of (PPr3)-Pr-n instead of the quarternary ammonia salt leads in toluene to the formation of crystalline [Zn8Se(SePh)(14)((PPr3)-Pr-n)(2)] 3. R eactions of ZnCl2 with PhTeSiMe3 and tertiary phosphines result in ace tone in crystallisation of the ionic clusters [(HPPr2R)-Pr-n](2)[Zn8Cl 4Te(TePh)(12)] (R = Pr-n 4, Ph 5) and in THF of the uncharged [Zn10Te4 (TePh)(12)(PR3)(2)] (R = Pr-n 6, Ph 7). The structures of 1-7 were obt ained by X-ray single crystal structure.
