摘      要：The title compound Co 3(CO) 9( μ 3 C)C(O)OCH 2 2 was synthesized by the reaction of Cl 3CC(O)OCH 2 2 with Co 2(CO) 8 at 40￣50 ℃. Crystal data: C 24 H 4O 22 Co 6, M r =997.88, monoclinic, space group P2 1/n(#14), a=9.330(2), b=15.197(4), c=11.783(4) , β=91.16(2)°, V=1670.4(7)  3, Z=2, D c =1.984 g/cm 3 , μ (Mo Kα )=30.01 cm -1 , F(000)=972.00, T=293K , final R=0.045, R w =0.051 for 1936 observed reflections with I2σ(I) . The structure contains two centrosymmetric dimeric molecules in a unit cell, each of which has two tetrahedral skeletons (CCo 3) connected through a C(O)OCH 3CH 2OC(O) bridge.
