摘要：
The crystal and molecular structure of the title compound K(C14 H20O5)2AuCl4 has been determined by X-ray diffraction method.The crystallographic data are as follows;Mr=914.51,triclinic,space group P1,a=10.988(2),b=13.472(4),c=13.696(2)A,α=77.72(1),β=79.02(2),γ=64.92(2)°,V=1782.6(4)A3,Z=2,Dc=1.704 g.cm-3,μ=45.858 cm-1,F(000)=454,R=0.019,Rw=0.018 for 5697 observed reflections with I≥3σ(I).X-ray structure determination shows that benzo-15-crown-5(B15C5)forms a 2:1 complex with KAu-C14 in which K+is sandwiched between two crown rings.The dihedral angle between these two ether oxygen planes is 11.9°.The anion AuCl4-has a planar square configuration which is bound with the complex cation K(B15C5)2+by electrostatic force to form an ion-pair.
