“…Though the nitrogen atoms of this amine molecule are part of the coordination requirement of the Cd atoms, it is likely that they may be amenable to chemical manipulations. Similar behavior of the piperazine molecules bound to metal centers and projecting into channels has also been observed in a three-dimensional cobalt pyromellitate …”

“…Extensive investigations by many researchers have given rise to a large number of coordination polymers with interesting structural, physical and chemical properties . Of the many benzene carboxylate compounds that have been prepared and characterized, those of the pyromellitic acid have been of interest to us. − The variations in the binding modes of the four acid functional groups combined with the coordination preferences of the metal ions are important in giving rise to the many different coordination polymers. We have been focusing our attention on the preparation of benzene carboyxlate coordination polymers in the presence of organic amine molecules.…”

Two new coordination polymers of the pyromellitic acid, [Zn(2)(H(2)O)(C(10)H(2)O(8))(C(4)N(2)H(8))]( infinity ), I, and [Cd(4)(H(2)O)(2)(C(10)H(2)O(8))(2)(C(4)N(2)H(8))(3)]( infinity ), II, have been prepared employing hydrothermal methods in the presence of piperazine. The structures have three-dimensional connectivity involving both the carboxylate and the amine molecule. The amine molecule acts as a ligand connecting two different metal centers giving rise to a simple dimer in I, and a two-dimensional layer structure in II. There are two types of pyromellitates in I and only one type in II. Of the two types of acids in I, acid-1 has all the oxygen atoms connected to Zn with monodendate connectivity and acid-2 has only four monodendate connectivity and possesses four terminal C-O linkage. In II, two of the carboxylates have bidendate connectivity and the other two have monodendate connectivity and possess one terminal C-O bond. The projection of the bound amine molecules, in II, into the large elliptical channels is noteworthy. These amine molecules may be amenable for chemical manipulations. Both the coordination polymers exhibit photoluminescence at room temperature, the main emission being at 380 and 410 nm, respectively, for I and II, which is due to the ligand-to-metal charger transfer (LMCT).

“…Employing the method of Trömel [38,39] the bond order is calculated to 2.20 [Cu(1)] and 1.94 [Cu(2)], respectively. Chiang et al [45] reported on a similar hydroxo-bridged tetranuclear unit in a cobalt benzene-1,2,4,5-tetracarboxylate. The monodentate coordination between the benzene-1,2,4,5-tetracarboxylate anions and the Cu 2+ cations builds up a threedimensional framework with large channel-like voids along [001] ( Figure 7 and Figure 8).…”

Triclinic single crystals of Cu 4 (H 3 N-(CH 2 ) 9 -NH 3 )(OH) 2 [C 6 H 2 (COO) 4 ] 2 ·5H 2 O were prepared in aqueous solution at 80°C in the presence of 1,9-diaminononane. Space group P1 (no. 2) with a = 1057.5(2), b = 1166.0(2), c = 1576.7(2) pm, α = 106.080(10)°, β = 90.73(2)°and γ = 94.050(10)°. The four crystallographic independent Cu 2+ ions are surrounded by five oxygen atoms each with Cu-O distances between 191.4(3) and 231.7(4) pm. The connection between the Cu 2+ coordination polyhedra and the [C 6 H 2 (COO) 4 ] 4anions yields three-dimensional framework with negative excess charge and wide
