Hydrothermal reactions of mixed ligands 5-sulfosalicylic acid (H(3)SSAL) and macrocyclic oxamide complex (CuL) with M(ClO(4))(2)·6H(2)O (M = Mn, Gd and Cu) afford three new complexes, including [Mn(II)(2)Mn(III)(SSAL)(2)(CuL)(2)(OH)(H(2)O)(3)]n (1), {[Gd(2)(HSSAL)(2)(CuL)(4)(C(2)O(4))(H(2)O)(2)]·2H(2)O}(n) (2) and [Cu(2)(HSSAL)(2)(CuL)(4)]·2H(2)O (3) (CuL, H(2)L = 2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-diene). Complex 1 has very interesting mixed-valence manganese-copper Cu(II)Mn(II)Mn(III)Mn(II)Cu(II) units and consists of a 1D ladderlike chain formed by the linkage of copper(ii) and Mn(3) clusters via the oxamide and SSAL(3-) bridges. The structure of 2 consists of hexanuclear Cu(II)(4)Gd(III)(2) molecules and is arranged in a 1D ladderlike chain formed by the linkage of copper(ii) and gadolinium(iii) via the oxamide, oxalate and HSSAL(2-) bridges. Complex 3 is a hexanuclear Cu(II)(6) molecule including both oxamide and HSSAL(2-) bridges. The results of magnetic determination show pronounced antiferromagnetic interactions in 1 and 3, and ferromagnetic interactions in 2.

Solvothermal reactions of mixed ligands H(3)BTC and macrocyclic oxamide complexes (ML, M = Cu, Ni) with M(ClO(4))(2)·6H(2)O (M = Co, Zn, Ni and Cd) afford six new complexes, including [M'(4)(BTC)(2)(ML)(2)(OH)(2)(H(2)O)(2)]·2H(2)O (M' = Co, M = Ni, for (1); M' = Zn, M = Ni, for (2); M' = Zn, M = Cu, for (3)), [Ni(3)(BTC)(2)(NiL)(2)(H(2)O)(6)]·2CH(3)OH·2H(2)O (4), [Cd(4)(BTC)(2)(HBTC)(NiL)(4)(H(2)O)]·3H(2)O (5) and [Cd(HBTC)(CuL)]·H(2)O (6) (ML, H(2)L = 2, 3-dioxo-5, 6, 14, 15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-dien; H(3)BTC = 1,3,5-benzenetricarboxylic acid). Complexes 1-3 consist of a 2D layer framework formed by the linkage of M(II)(M = Ni, Cu) and M'(4) (M' = Co, Zn) cluster via the oxamide and BTC(3-) bridges and display a (3,6)-connected network with a (4(3))(2)(4(6).6(6).8(3)) topology. The structure of 4 consists of pentanuclear [Ni(II)(5)] units and arranges in a 1D cluster chain. Complex 5 exhibits a 2D layered structure characterized by 3,4,3-connected (4.6(2))(3)(4.6(3).8(2))(4(2).6(3).8)(4(2).6) topology. Complex 6 possesses a 3D network with sra topology. The magnetic properties of complexes 1 and 4 were investigated.

Two novel heteronuclear complexes [Cd3(SSAL)2(CuL)2(H2O)4]n (1) and [Cd2(HSSAL)2(NiL)4]·4H2O (2) were synthesized and structurally determined, where SSAL is the fully deprotonated 5‐sulfosalicylic ion (CuL and NiL, H2L = 2,3‐dioxo‐5,6,14,15‐dibenzo‐1,4,8,12‐tetraazacyclopentadeca‐7,13‐diene). Compound 1 displays a 1D ladder‐like chain and all these chains are further interlinked through hydrogen bonds resulting in a 2D architecture. The structure of 2 consists of 5‐sulfosalicylates and an oxamido‐bridge and is arranged in butterfly‐like hexanuclear molecules. The luminescent properties of compounds 1 and 2 are also discussed.

Three novel complexes, namely [Zn(CuL)(pzdc)]2·5H2O (1), [Zn(NiL)(pzdc)]2·5H2O (2), and [Gd2(pzdc)2(NiL)6](ClO4)2·6H2O (3) (CuL and NiL, H2L = 2, 3‐dioxo‐5, 6, 14, 15‐dibenzo‐1, 4, 8, 12‐tetraazacyclo‐pentadeca‐7, 13‐dien and H2pzdc = pyrazine‐2, 3‐dicarboxylic acid) were synthesized and structurally determined. Complexes 1 and 2 are tetranuclear [ZnII2MII2] (M = Ni (1), Cu (2), respectively) molecules including both oxamide and pzdc2– bridges. The structure of compound 3 consists of pyrazine‐2, 3‐dicarboxylate and oxamido‐bridged, and is arranged in different butterfly‐like octanuclear molecules. The magnetic susceptibility data of 3 were analyzed.
