摘要: 双—(噻吩甲酰三氟丙酮)合铜晶体属三斜晶系,空间群为Ci—P1。晶胞参数:a=4.573(2)Å,b=9.291(4)Å,c=11.059(6)Å,α=80.87(4)°,β=77.09(5)°,γ=79.23(5)°,V=446.5Å°Z=1,Dc=1.889g·cm-3,F(000)=253e。由于空间位阻效应,在双—(噻吩甲酰三氟丙酮)合铜的分子中,两个噻吩基呈反式构型。对二甲亚砜加合物中两个噻吩基取顺式构型的原因作了进一步阐明。 |

Abstract: The crystal structure of CuCTTA)2 has been determinded by X-ray diffraction method.The cryatal belongs to triclinic system with a= 4.753(2)Å, b=9.291(4)Å, c = 11.056(6)Å, α= 80.87(4)°, β=77.09(5)°,γ = 79.23(5)°, V= 446.5Å; space group C11-P1; Z=1, Dc= 1.899g·cm-3, M=507.91, F(000) = 253e.The structure was solved by heavy atom method and refined by least square technique to a final discrepancy factor of R= 0.072.It is shown that two molecules of thenoyltrifluoro-acetone with Cu(Ⅱ) form a trans-coordination compound, due to space hindered effect.Using the space effect of molecule (CH32SO, we have a better understanding the origin of that two molecules of thenoyltri-fluoroacetone form a cis-coordination compound in Cu(TTA)2·(CH3)2-SO. |
