“…Among the s-block metals are Li,5,6 Na, K, Cs, 7 Ca, 8 and Mg, 9 whereas the d block metals include Co 10 and Cu, [11][12][13][14][15] alkali metal-Cu, 16 Mn, [17][18][19] Fe, 20 Ni, 21,22 Ti, 23 Cd, [24][25][26] and Ag. 27 All, except Cd, crystallize as 1-D chains or 2-D layered CPs. In some cases the structures extend into 3-D networks through hydrogen bonding.…”

“…Further, several of the reported structures, contain pztc in combination with other co-ligands, including, pyridine 11,22,25 and 2,2′-bpyridine. 27 It also noteworthy that partial deprotonation of H 4 pztc to H 2 pztc 2− can occur during synthesis, leading to significant intra-ligand hydrogen bonding within the resulting MOF and CP structures. 19,20 This may limit the extent of multidimensional connectivity that could otherwise be attained.…”

Metal-organic frameworks {[Ln 4 Ĳpztc) 3 ĲH 2 O) 11 ]·10ĲH 2 O)} n (Ln = GdĲ1), TbĲ2); pztc = pyrazine-2,3,5,6tetracarboxylate) containing variable coordination spheres and with a complex and unusual three dimensional structure, were synthesized by the reaction of H 4 pztc with the respective LnĲIII) salt in water under hydrothermal conditions. The compounds were characterized by single crystal X-ray crystallography, elemental and thermal analysis, and FTIR spectroscopy. The asymmetric units in these compounds have four symmetry-independent LnĲIII) ions and these are octa-and nona-coordinate centers, with irregular coordination polyhedra from ĳLnĲpztc) 2 ĲH 2 O) 6 ], ĳLnĲpztc) 2 ĲH 2 O) 4 ], ĳLnĲpztc) 3 ĲH 2 O) 3 ], ĳLnĲpztc) 3 ĲH 2 O)], and ĳLnĲpztc) 4 ] cluster units. The fully deprotonated ligand, pztc, coordinates to the Ln 3+ ions through seven or through ten of its atoms (i.e., the maximum coordination number for this ligand). The three-dimensional open framework contains irregular channels along the [001] crystallographic direction. The channels are approximately 12 Å wide at their largest dimension and contain strongly hydrogen bonded water molecules of crystallization which further stabilize the structure. The solvent accessible volume is 20% of the total volume. The structures exhibit magnetic behavior that is characteristic of the respective isolated paramagnetic lanthanide ions.

“…Structural elaboration and topological variance in these complexes can be enhanced by incorporation of neutral ligands such as 4,4′-bipyridine (bpy), 1,2-bis(4-pyridyl)ethylene (dpee), 1,2-bis(4-pyridyl)ethane (dpe), or 1,10-phenanthroline (phen) via adjustment of the carboxylate bridge [24][25][26]. A number of cobalt(II) and silver(I) coordination polymers have been constructed from polycarboxylates such as phthalate [27], terephthalate [28], isophthalate [29], biphenyl-2,2′,4,4′-tetracarboxylic acid [30], 3,3′,4,4′-benzophenonetetracarboxylic [31], and pyrazine-2,3,5,6-tetracarboxylic acid [32], which provide both the charge balance and structural rigidity necessary for self-assembly. We (2).…”

Two new coordination polymers with an asymmetric dicarboxylate and 4,4′-bipyridine ligand, {[Co (bpy)(H 2 O) 4 ]·(cpa)·0.5H 2 O} n (1) and {[Ag(cpa)(bpy)][Ag(bpy)]·4H 2 O} n (2) (H 2 cpa = 4-(2-carboxyethyl)benzoic acid, bpy = 4,4′-bipyridine), have been hydrothermally synthesized and characterized by elemental analysis, FT-IR spectroscopy, and single-crystal X-ray diffraction. Compound 1 displays a chain with guest molecule (cpa) 2− ions existing in the structure. Compound 2 contains two independent units, [Ag(cpa)(bpy)] -(A) and [Ag(bpy)] + (B), which form a 1-D + 1-D structure. A shows a 1-D chain structure bearing hooks formed by the carboxylates and organized into a tubular structure by hydrogen-bonding interactions. B has linear chains formed from Ag + and bpy. The A and B chains co-crystallize with waters of crystallization to provide two linear [Ag(bpy)] + chains embedded in the tubular structure formed by A via π…π stacking contacts. In 1 and 2, hydrogenbonding and π…π stacking interactions connect the discrete 1-D chains into 3-D supramolecular structures. The fluorescent properties, TG analysis, and X-ray powder diffraction patterns for 1 and 2 were also measured.
