一维链状冠醚配合物:[{Na(18-C-6)}_2(H_2O)]_n[M(SCN)_4]_n(M=Pd、Pt)的合成与结构

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.
