A new compound[CpCo(Se_2C_2B_(10)H_9)CH_2C(O)C_4H_3O]has been synthesized and characterized by elemental analysis,IR spectroscopy,NMR,MS and single-crystal X-ray diffraction.The complex crystallizes in the monoclinic system,space group P2_1/c with a=10.9481(10),b=24.6600(12),c=25.7430(14)A,β=100.863(3)°,C_(42)H_(57)B_(30)Co_3O_6Se_6·CH_2Cl_2·0.25H_2O,M_r=1722.16,V=6825.6(8)A~3,D_c=1.676 g/cm~3,Z=1 and F(000)=3346.The molecular structure shows a 1:1 ratio product of the two reactants of 16e half-sandwich complex CpCo(Se_2C_2B_(10)H_(10))and alkyne 1-(2-furyl)-2-propyn-1-one.The hydrogen atom in the B(3)position of CpCo(Se_2C_2B_(10)H_(10))has been activated and migrated to the terminal carbon of 1-(2-furyl)-2-propyn-1-one to form the B-CH_2 unit.The title compound molecules are linked and extended further into a one-dimensional chain through atypical hydrogen bonds.
