Abstract
This article represents two types of entanglements, [Co2(bibp)(BTB)2][Co(bibp)2(H2O)2] (1) and [Co3(bibp)2(H2O)2(BTB)2]·2H2O·2DMF (2) (bibp = 4,4′-bis(1-imidazolyl)biphenyl and H3BTB = 1,3,5-tris(4-carboxyphenyl)benzene), which are 2-D→3-D polycatenated frameworks formed by parallel catenation of 1-D+2-D→2-D polythreaded motifs based on the double-layered sheet penetrated by ribbons of rings (1) and a 2-D→3-D mutual polythreading of three double-layered sheets with dangling arms (2), which is assembled by the same initial materials by simply changing the volume ratio of water/DMF medium.
