Abstract

Reactions of the angular 4,4′-oxybis[N-(pyridin-3-ylmethyl)benzamide] (L) with dicarboxylic acids and transition metal salts afforded non-entangled {[Cd(L)(1,3-BDC)(H2O)]∙2H2O}n (1,3-BDC = 1,3-benzenedicarboxylic acid), 1; {[Cd(L)(1,4-HBDC)(1,4-BDC)0.5]∙2H2O}n (1,4-BDC = 1,4-benzenedicarboxylic acid), 2; {[Cu2(L)2(1,3-BDC)2]∙1.5H2O}n, 3; {[Ni(L)(1,3-BDC)(H2O)]∙2H2O}n, 4; {[Zn(L)(1,3-BDC)]∙4H2O}n, 5; {[Zn(L)(1,4-BDC)]∙2H2O}n, 6; and [Cd3(L)2(1,4-BDC)3]n, 7, which have been structurally characterized by using single-crystal X-ray diffraction. Complexes 1–5 and 7 are 2D layers, giving (64·8·10)(6)-2,4L3, (42·82·102)(42·84)2(4)2, (4·5·6)(4·55·63·7)-3,5L66, (64·8·10)(6)-2,4L3, interdigitated (84·122)(8)2-2,4L2 and (36·46·53)-hxl topologies, respectively, and 6 is a 1D chain with the (43·62·8)(4)-2,4C3 topology. The factors that govern the structures of 1–7 are discussed and the thermal properties of 1–7 and the luminescent properties of complexes 1, 2, 5 and 6 are investigated. The stabilities of complexes 1 and 5 toward the detection of Fe3+ ions are also evaluated.
