Two triangular molybdenum-tellurium clusters, Mo3Te7-[S2CN (CH2CH2OH)2]3I (1) and MosTe4Y3[S2P(iPrO)2]3I (Y3 = 1.43Te+ 1.57S) (2), were obtained from the reaction of K@HOdtc [HOdtc= S2CN(CH2CH2OH)2] or K@iPr2dtp (iPr2dtp = S2P[OCH(CH3)2]2) with a mixed product of elements Mo,Te(S) and I2 at high temperature. The structures of the two compounds were determined by X-ray crystallography study.Crystal data are, (1): monoclinic, P21/n, a = 1.6256(3), b =1.3264(2), c= 1.8808(4) nm, β=96.923°, V=4.025.9(14) nm3, Dcal=3.050 g@ cm-3, Z=4, and (2): monoclinic,P21/n, a=1.4564(2), b=2.3917(4), c=1.5094(3) nm, β = 114.35(2)°, V=4.0259(14) nm3, Dcal=2.449 g@cm-3 and Z=4. Single crystal analyses show that 1 consists of discrete Mo3Te7[S2CN(CH2CH2OH)2]3I connected into three-dimensional framework via hydrogen bonds, while 2 forms a linear chan via Te(S)-I interaction.
