摘　　要：The reaction of Ru3(CO)12 with P(NEt2)2Cl, yields two trinuclear ruthenium carbonyl clusters: HRu3(CO)9[ μ3-η2-P(NEt2)2]2 Ⅰ (known) and a novel Ru3(CO)7( μ-Cl)2[ μ-P(NEt2)2]2 Ⅱ. During the reaction, the ligand precursor was cleaved in its P-Cl bond to give the fragments Cl and P(NEt2)2, and then coordinated to the ruthenium atoms to form the clusters as listed above. The crystal structure of cluster Ⅱ has been determined by X-ray diffraction technique. The crystal belongs to monoclinic with space group P21 / c. The unit cell parameters are as follows: a=1.287 9(6) nm, b=1.653 9(8) nm, c=1.643 6(8) nm, β=95.786(7)°, V=3.483(3) nm3, Dc=1.756 g·cm-3, Z=4. The cluster has a closed triangle Ru3 framework. Two Ru-Ru bonds are supported by μ-P(NEt2)2, the other one is connected by double Cl bridging. The valence electrons of the cluster are 50e. CCDC: 231979.The reaction of Ru3（CO）12 with P（NEt2）2Cl, yields two trinuclear ruthenium carbonyl clusters;HRu3（CO）9 [μ3-η^2-P（NEt2）2]Ⅰ （known） and a novel Rus（CO）7（μ-Cl）2[μ-P（NEt2）2]2Ⅱ.
