摘　　要：The reactions of 18-crown-6with Na 2M(SCN)4(M=Pd,Pt )were studied and the complexNa (18-C-62 (H2O) nPd(SCN)4 n and complex2Na (18-C-6) 2 (H 2 O nPt (SCN) 4 n were characterized by ele-mental analysis,IR and X-ray diffra ction analysis.The complexes belon g to monoclinic,space group P2 1 /n with cell dimensions,1:a=1.05734(7),b=1.42250(10),c=1.47762(10)nm,β=107.5330(10)°,V=2.1192(2)nm 3 ,Z =2,D calcd =1.460g·cm -3 ,F(000)=964,R 1 =0.0406,w R 2 =0.1264and2:a=1.05985(19),b=1.4237(3),c=1.4744(3)nm,β=107.096(3)°,V=2.1264(7)nm 3 ,Z =2,D calcd =1.690g·cm -3 ,F(000)=1028,R 1 =0.0292,w R 2 =0.0859.In the solid state,the comp lexes1and2show an one-dimensnal chain ofNa (18-C-6)狚 2 (H 2O)2+ complex cations andM(SCN) 4 2- (M=Pd,Pt )complex anions bridged by Na-N in-teractions.The reactions of 18-crown-6 with Na-2[M(SCN)(4)] (M = Pd, Pt) were studied and the complex 1 [{Na (18-C-6)}(2)(H2O)](n)[Pd(SCN)(4)](n) and complex 2 {Na(18-C-6)}(2)(H2O)](n)[Pt(SCN)(4)](n) were characterized by elemental analysis, IR and X-ray diffraction analysis. The complexes belong to monoclinic, space group P2(1)/n with cell dimensions, 1: a = 1.05734(7), b = 1.42250(10), c = 1.47762 (10) nm, beta = 107.5330(10)degrees, V = 2.1192 (2) nm(3), Z = 2, D-caled = 1.460g . cm(-3), F (000) = 964, R-1 = 0.0406, w R-2 = 0.1264 and 2: a = 1.05985 (19), b = 1.4237(3), c = 1.4744 (3) nm, beta = 107.096 (3), V = 2.1264 (7) nm(3), Z = 2, D-caled = 1.690g . cm(-3), F(000) = 1028, R-1 = 0.0292, w R-2 = 0.0859. In the solid state, the complexes 1 and 2 show an one-dimensional chain of [{Na(18-C-6)}(2)(H2O)](2+) complex cations and [M(SCN)(4)](2-) (M = Pd, Pt) complex anions bridged by Na-N interactions.
