Abstract
Self-assembly of NiII/CoII with 4,4′-sulfonyldibenzoic acid (H2E1) and 1,4-bis(1,2,4-triazole-1-ylmethyl)benzene (pbtx) has produced 3-D interpenetrated polythreading networks with non-trivial linkages, [{Ni(pbtx)(E1)(H2O)}·H2O]n (1) and [{Co(pbtx)(E1)(H2O)}·H2O]n (2), respectively. Single-crystal X-ray diffraction analyses revealed that 1 and 2 are isomorphous and isostructural. Complexes 1 and 2 possess a 2-D grid layer consisting of metal ions bridged by pbtx ligands and entirely deprotonated E12− ligands, which led to the formation of 2-fold interpenetrated polythreading networks. The interpenetrated networks were further bridged by C–H⋯O and O–H⋯O hydrogen bonds to generate their 3-D frameworks. Further characterizations including elemental analysis, FT-IR, XPRD, and Thermogravimetric analysis have been studied. Two 2-fold interpenetrated polythreading networks, [{Ni(pbtx)(E1)(H2O)}·H2O]n (1) and [{Co(pbtx)(E1)(H2O)}·H2O]n (2), were constructed by aromatic polycarboxylic acid H2E1 (H2E1 = 4,4′-sulfonyldibenzoic acid) and pbtx (pbtx = 1,4-bis(1,2,4-triazole-1ylmethyl)benzene). 1 and 2 show distinctive new interpenetrated structure of two identical single nets interlocked with each other via rotaxane-like links.
