Abstract: The reactions of (μ3-CCO2Et)Co3 (CO)9 with [Mo(CO)3(η5-C5H4R)]-[R = H or C(O)Me] gave rise to the formation of (μ3-CCO2Et)Co2Mo(CO)8(η 5-C5H4R) [R = H (1), C(O)Me(2)]. The further reaction of cluster 1 or 2 with {(M(CO)3[η5-C5H4C(O)]} 2-1, 4-C6H4[M = Mo or W] yielded four linked clusters {(μ3-CCO2Et)CoMoM(CO)7(η 5-C5H4R)[η5-C5H 4C(O)]}2-1, 4-C6H4[M = Mo, R = H(3); M = Mo, R = C(O)Me(4); M = W, R = H(5); M = W, R = C(O)Me(6)]. All these clusters were characterized by C/H analyses, IR and 1H NMR. The crystal structure of cluster 2 was determined by single-crystal X-ray diffraction method. The crystal belongs to monoclinic system with space group, C2/c and lattice parameters, a = 1. 126 4 (3) nm, b = 1. 187 9(3) nm, c = 3. 356 5(10) nm, β = 93. 320(5)°, V = 4. 484(2) nm3, Z = 8, Dc = 1. 867 g · cm-3, F(000) = 248 0, R = 0. 036 9, wR = 0. 115 0.
