【Abstract】 The reactions of benzo 18 crown 6 (B18 C 6) with K 2 (M=Pd, Pt) were studied and the complexes [K(B18 C 6)] 2[Pd(SCN) 4] (1), [K(B18 C 6)] 2[Pt(SCN) 4] (2) and [K(B18 C 6)] 2[PtSCN 4]·C 2H 4Cl 2(3) were characterized by elemental analysis, IR and X ray diffraction analysis. 1 and 2 belong to monoclinic, space group P 2 1/ n with crystal data: 1, a =1 00970(17) nm, b =1 3157(2) nm, c=1 7303(3) nm, β =94 954(2)°, V =2 2902(7) nm 3, Z =2, F (000)=1072, R 1=0 0267; 2, a =1 00908(18) nm, b =1 3124(2) nm, c =1 7317(3) nm, β =94 841(2)°, V =2 2852(7) nm 3, Z =2, F (000)=1136, R 1=0 0257. 3 belongs to triclinic, space group P 1 with crystal data: a =0 95914(18) nm, b =1 2137(2) nm, c =1 2313(2) nm, α =63 693(2)°, β =76 293(2)°, γ =78 353(2)°, V =1 2406(4) nm 3, Z =1, F (000)=618, R 1=0 0366. In the solid state, the complexes exhibit one dimensional chain structure of two [K(B18 C 6)] + complex cations bridged by K atom and O atom of crown ether between adjacent complex cations.
