Syntheses, structures and characterizations of coordination polymers based on two new resorcin[4]arene carboxylic acids

Through use of two novel resorcinpljarene-based carboxylic acids, [Ni-2(H4L1)(teta)(2)]center dot 3H(2)O (1), [Ni(H6L1) (teta)]center dot 0.5C(2)H(5)OH center dot 2H(2)O (2), [Cu(H6L1)(teta)]center dot 3.5H(2)O (3), [Ni(cyclam)(OH)(2)]center dot 2H(8)L(1)center dot C2H5OH center dot 4H(2)O (4), [Cu (cyclam)Cl-2]center dot 2H(8)L(1)center dot 3C(2)H(5)OH (5), [Cu-2(L-2)(cyclam)(2)]center dot 2H(2)O (6) [Mn-2(L-2)(H2O)(3)]center dot 2DMF center dot 5H(2)O (7) and [(CH3)(2)NH2][Cd-3(L-2)(HL2)(DMF)(2) (H2O)(3)]center dot DMF center dot 5H(2)O (8) (H8L1 = 2,8,14,20-tetra-ethyl-4,10,16,22-tetrakis ((3,5-dicarboxybenzyl)oxy)-6,12,18,24-tetra-methoxy-resorcin[4]arene, H4L2 = 2,8,14,20-tetra-ethyl-4,10,16,22-tetrakis((3-carboxybenzyl)oxy)-6,12,18,24-tetra-methoxy-resorcin[4]arene, teta = 5,5,7,12, 12,14-hexamethy1-1,4,8,11-tetraazacyclotetra decane and cyclam = 1,4,8,11 -tetraazacyclotetradecane) have been synthesized. Compounds 1 and 6 exhibit infinite ribbons. 2 and 3 are isomorphous and produce chain structures. Isostructural 4 and 5 show unique mononuclear structures. Hydrogen-bonding interactions further link 1-5 to form three-dimensional (3D) supramolecular structures, respectively. 7 gives a layer structure produced by tetranuclear Mn(11) clusters. 8 yields a 3D framework. UV-Vis spectra were studied for all compounds. The variable temperature magnetic susceptibility of 1 has been investigated. The luminescent property of 8 has also been studied. (C) 2017 Elsevier Ltd.
