Popis: A unique 3D entangling Cu(II)-metal organic framework, namely, {[Cu 4 (abtc) 2 (btab) 6 ·3H 2 O]·2H 2 O} n ( 1 ), has been successfully constructed from Cu II and 3,3′,5,5′-azo benzene tetracarboxylate building units with the aid of N-donor bridging spacers [1,4-bis(triazol)butane], and directs a rare self-penetrating structure with polyhelix motifs and presents a new (4,4,8)-connected (4.6 5 ) 2 (6 4 .7.8) 2 (4 2 .6 20 .7 2 .8 4 ) topology. The magnetic investigations demonstrate that complex 1 exhibits antiferromagnetic coupling interaction between the adjacent Cu(II) ions.
