Abstract

Abstract: Six new dimolybdenum alkyne compounds[Mo(CO)₂(η⁵-C₅H₄R¹)]₂(μ-η²,η²-(CH=CR²)[R¹=C(O)Me,R²=Ph,1; R¹=C(O)OEt,R²=Ph,2;R¹=C(O)Ph,R²=Ph,3; R¹=C(O)Me,R²=CH₂OH,4;R¹=C(O)OEt,R²=CH₂OH,5;R¹＝C(O)Ph,R²＝CH₂OH,6] have been synthesized by the reaction of alkyne with [Mo(CO)₂(η⁵-C₅H₄R¹)]₂[R¹=C(O)Me,C(O)OEt,C(O)Ph]and characterized by C/H analysis, IR and ¹HNMR.The crystal structure of compound 1 was determlned by single crystal X-ray diffraction anal-ysis.Compound 1 crystallized in monoclinic, space group P2₁, (#4), a= 0.7671 (2) nm, b=0.8365(2) nm, c=1.8308(3) nm, β=98.34(1)°, V=1.1623(5) nm³, Z=2, D_c=1.772g·cm^-3, F(000)=616, R=0.041, R_w=0.045.
