摘要
合成了配合物[(PhCH2CH2O)2PS2]3Cr并由元素分析、IR、UV-Vis、热重分析和X-射线衍射等进行了结构表征.该晶体属于三斜晶系,P-1空间群;晶胞参数为:a=l.39418(3)nm,b=1.40150(3)nm,c=1.47012(3)nm,α=76.3126(19)°;,β=101.033(3)°,γ=78.7534(17)°,V=2.61241(9)nm3,Dc=1.353Mg·m-3,Z=2,F(000) =1110,μ(Mo Kα) =0.596mm-1,S=1.019,(△/σ)max =0.001,R1=0.0512,wR2=0.1576 (I>2σ-(I)).配合物中的(PhCH2CH2O)2PS2-为双齿配体,Cr原子与3个配体(PhCH2CH2O) 2PS2-的6个S原子配位形成了畸变八面体构型,Cr-S键长为0.24193(9) ~ 0.24476(9)nm.
Complex [ ( PhCH2 CH20) 2PS2] 3 Crwas synthesized and characterized by elemental analysis, IR, UV-Vis, TG-DSC, XRD. The complex crystallized in triclinic, P-1 space group with the cell parameters: a=l.39418(3)nm,b=1.40150(3)nm,c=1.47012(3)nm,α=76.3126(19)°;,β=101.033(3)°,γ=78.7534(17)°,V=2.61241(9)nm3,Dc=1.353Mg·m-3,Z=2,F(000) =1110,μ(Mo Kα) =0.596mm-1,S=1.019,(△/σ)max =0.001,R1=0.0512,wR2=0.1576 (I〉2σ-(I)).In this complex, the chromium( Ⅲ) coordinates with six sulfur atoms from three ligands of (PhCH2CH2O)2PS2 - and locates at the center of the distorted octagonal. The bond length for Cr-S is in the range of 0. 24193(9) - 0. 24476(9)nm.
