摘要：
Two new complexes [{CuL}Sm(H2O)(3){Fe(CN)(6)}](2)center dot 6H(2)O (1) [{CUL}(2)Pr(H2O){Fe(CN)(6)}](2)center dot 4H(2)O (2) (H2L = N,N'-ethylenebis(3-methoxysalicylideneimine)) have been prepared by reactions of acyclic compartmental Schiffbase heterodinuclear 3d-4f compound [{CuL}Ln(NO3)(3)] (Ln = Sm & Pr) with K-3[Fe(CN)(6)]. Crystal structures of both 1 and 2 reveal unique topology structures. 1 shows a dimeric heterotrinuclear [(CuL)Sm(H2O)(3){Fe(CN)(6)}](2) while 2 displays a dimeric heterotetranuclear [{CuL}(2)Pr(H2O){Fe(CN)(6)}] with distorted sandwich moieties [{CuL}(2)Pr]. Both 1 and 2 form similar 10 ladder-like structure through the intermolecular double bridges of Cu-N bonds. The measurement of variable-temperature magnetic susceptibility reveals that both complexes 1 and 2 exhibit antiferromagnetic interaction between spin carriers. (C) 2014 Published by Elsevier B.V.
