“…Recently, the design and synthesis of coordination compounds have attracted much attention due to their structural diversity [1-2] and potential applications [2][3][4][5][6][7][8].Asuccessful strategy for preparing coordination compounds is the assembly reaction between atransition metal ion and two types of organic molecules, one acting as aterminal ligand and the other as abridging ligand. In this aspect, the rigid and versatile ligand 2-(4'-chlorobenzoyl)benzoic acid (Hcbba) has been relatively less studied for constructing coordination compounds containing transition metals [9][10].…”

Source of materialAmixture of Mn(CH 3 COO) 2 ) × 4H 2 O(0.2 mmol, 0.05 g), 2-(4'-chlorobenzoyl)benzoic acid (0.4 mmol, 0.10 g), 2,2'-bipyridine (0.2 mmol, 0.032 g) and H 2 O(18 mL) was placed in a30mLTef-lon-lined autoclave under autogenous pressure at 423 Kfor seven days. After cooling to room temperature, yellow block-shaped crystals were collected by filtration and washedw ith distilled water in 42 %yield (based on Mn).

In the title crystal structure, the asymmetric unit contains one and ahalfMn(II) atoms, three2-(4'-chlorobenzoyl)benzoate (cbba) ligands and one 2,2'-bipyridine ligand. The Mn1 atom is six-coordinated by six carboxylate oxygen atoms( O1,O 4, O5,O 1A, O4A, O5A) from six different cbba ligands, forming as lightly

“…During the past decades, polycarboxylates have become one of the most used spacers in the synthesis of compounds that have potential applications as molecular-based magnetic materials, and for the preparation of porous materials that show host-guest behavior [1][2][3][4][5]. However, hydroxypolycarboxylic acids, although important as polycarboxylate ligands, have been seldom used for such preparations.…”

Source of materialA mixture of NiCl 2 · 6H 2 O (0.1 mmol), 2,3-dihydroxybutanedioic acid (0.10 mmol), NaOH (0.20 mmol), 1,10-phenanthroline (0.20 mmol) and water (10 mL) was stirred for 30 min in air, then sealed in a 25 mL Teflon-lined stainless steel container, which was heated to 130°C for 72 h. After cooling to room temperature at a rate of 2 K per hour, light-green block crystals were obtained in ca. 40 % yield base on Ni. Experimental detailsWhile the hydrogen atoms of all water molecules were located from Fourier difference maps and refined using bond restraints, the other H atoms were fixed at calculated positions and not refined. DiscussionDuring the past decades, polycarboxylates have become one of the most used spacers in the synthesis of compounds that have potential applications as molecular-based magnetic materials, and for the preparation of porous materials that show host-guest behavior [1][2][3][4][5]. However, hydroxypolycarboxylic acids, although important as polycarboxylate ligands, have been seldom used for such preparations. In the title crystal structure the nickel(II) is in a distorted octahedral environment formed by two oxygen atoms (d(NiO3 = 2.094(3) Å and d(NiO1) = 2.018(3) Å) from one 2,3-dihydroxybutanedicarboxylate dianion ligand and four nitrogen atoms from two 1,10-phenanthroline molecules (figure top).

Adsorption processes are among the most patronized applications of Metal-Organic Frameworks.Through adsorption MOFs have found usefulness in diverse sectors of human endeavors such as; removal of noxious and harmful substances (dyes and heavy metals from liquid/gaseous media discharged from industries), storage and sequestration of gases (carbon dioxide, methane and hydrogen), separation and purification of gases/petroleum products, catalytic processes and drug delivery. Functionalized MOFs can indeed show spectacular effects owing to the introduction of more active functional groups. Therefore, the performance and applicability of MOFs as sorbents in industrial processes depends on the degree of introduced functionality, high surface area and enhanced porosity.
