摘要
A new compound [CpCo（Se2C2BIoH9）CH2C（O）C4H30] 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 P21/c with a = 10.9481（10）, b = 24.6600（12）, c = 25.7430（14） A, β = 100.863（3）°, C42H57B30Co306Se6＂CH2C12＂0.25H20, Mr = 1722.16, V = 6825.6（8） A3, Dc= 1.676 g/cm3, 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（Se2C2B10H10） and alkyne 1-（2-furyl）-2-propyn-l-one. The hydrogen atom in the B（3） position of CpCo（Se2C2B10HIo） has been activated and migrated to the terminal carbon of 1-（2-furyl）- 2-propyn-l-one to form the B-CH2 unit. The title compound molecules are linked and extended further into a one-dimensional chain through atypical hydrogen bonds.
