英文摘要	Two heterobinuclear cyano-bridged RE-Fe complexes RE(dpdo)(2)(H2O),Fe(CN)(6). 4H(2)O (RE=Gd,Y; dpdo=2,2'-Dipyridyl N,N'-Dioxide) were synthesized with identical structure. Gd-Fe complex crystallizes in triclinic crystal system, space group P-I with a=10.305(2), b=12.475(1), c=13.903(1)Angstrom, alpha=85.34(1), beta=88.08(1), gamma=70.54(1)degrees, V=1679.6(4) Angstrom(3) Z=2. In Gd-Fe binuclear unit, Gd3+ is eight coordinated by one N atom from one CN- group, four O atoms from two bidentate dpdo molecules and three O atoms from water molecules, forming a square anti-prism. Gd and Fe are bridged via one CN- group from Fe(CN)(6)(3-) ion with Gd-Fe separation 5.507(1)Angstrom. The nearest inter-molecular distances of Gd-Fe, Gd-Gd, Fe-Fe are 7.457(1), 7.984(1), and 8.409(1)Angstrom, respectively. There are hydrogen bond intra- and inter-molecular connections. The intra-molecular coupling of Gd-Fe is weakly ferromagnetic, meanwhile the interactions between the binuclear units are weakly antiferromagnetic in character.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000083449600020&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Crystallography; SCI(E); CPCI-S(ISTP); 1
