“…In the construction of new supramolecular networks based on metal-containing complex, the polycarboxylate ligands are of special interest [1][2][3][4]. They can be regarded not only as hydrogenbonding acceptors but also as hydrogen-bonding donors, depending upon the number of deprotonated carboxylate groups.…”

Source of materialAm ixture of 5-nitroisophthalic acid (NIP, 0.022 g, 0.1 mmol), Ni(CH 3COO)2 (0.018 g, 0.1 mmol), 2,2'-bipyridine (2,2'-bipy, 0.016 g, 0.1 mmol), and H 2 O( 10 mL) was stirred for about 30 min.The resulting solution was sealed in aTeflon-lined stainless autoclave and heated to 393 Kf or 3d ays. Experimental detailThe C-bound Ha toms were geometrically placed (d(C-H) = 0.93 Å)and refined as riding with U iso(H) =1.2 Ueq(C). The Obound Ha toms were located in difference maps and refined as riding in their as-found relative positions with U iso (H) =1 .2 U eq (O).

Source of materialThe mixture of Sm(NO 3 ) 3 · 6H 2 O( 0.085 g, 0.2 mmol) and 4-hydroxypyridine-2,6-dicarboxylic acid (H 3 CAM, 0.074 g, 0.4 mmol) was stirred into 15 ml aqueous solution and the pH value was adjusted to approx. 5with 1.0 Mammonia. Then 5mL ethanol solution of N,N-dimethylformamide (DMF, 1.0 mL) was added. The reaction mixture was heated on awater bath for 10 hat 70°C, then filtered. The resulting clear solution was diffused with diethyl ether vapor at room temperature for two weeks, blockshaped colourless crystals insoluble in water were obtained (yield 0.049 g, 36 %). Elemental analysis -found: C, 32.67 %; H, 3.19 %; N, 6.17 %; calculated: C, 32.95 %; H, 3.20 %; N, 6.06 %. IR data are available in the CIF. DiscussionDuring the past two decades, there has been growing interest in lanthanoids and their compounds because of the emergence of novel structure features and functional properties in different application fields [1][2][3]. The current attention is focused on the construction of rear earth metal-organic frameworks (MOFs) with novel topology and on the crystal engineering of molecular architectures organized by coordination bonds and supramolecular contacts (such as hydrogen bonding, p-p stack interactions, etc.) [4,5]. In this work, 4-hydroxypyridine-2,6-dicarboxylic acid (H 3 CAM) was employed as the major ligand because it has a unique configuration, which can potentially provide more coordination features [6,7]. The title crystal structure is composed of one Sm(III) ion, two HCAM 2-ligands, three coordinating water molecules, and two lattice water molecules as well as one dimethylammonium cation (DMA), which is in situ generated through the DMF solvent under the hydrothermal condition [8,9]. Each Sm(III) is ninecoordinated and exhibits atricapped trigonal prismatic environment formed by four oxygen atoms from the two carboxylate groups of HCAM 2-ligands, two nitrogen atoms from two pyridine rings, and three oxygen atoms from water molecules. Each HCAM 2-ligand adopts at ri-dentate coordination mode, employing one nitrogen and two oxygen atoms to chelate Sm(III) ion. The dimethylamine does not participate in the coordination due to its protonation under the acidic condition. This coordination mode can also be observed in the analogous lanthanide complexes [10]. The [Sm(HCAM) 2]unit carries one negative charge, while DMA bears one positive charge, thus maintaining the charge balance. The d(Sm-O) range from 2.416(4) to 2.624(2) Å,and d(Sm-N) range from 2.555(3) to 2.594(5) Å,which are within normal ranges [12]. The dihedral angle between the two pyridyl rings attached to the central Sm ion is 70.20°,and the angle of N1-Sm-N2 is 118.25°.B oth the pyridine ring and the dicarboxylate group of HCAM ligands are almost coplanar, and the atoms in the pyridine deviate from the least square plane defined by the pyridine ring by less than 0. 020 Å.Deviation from the mean plane defined by the pyridine ring are observed for both of carboxylic groups with values ranging from O2 -0.156(7) to O1 +0.153...

= 0.062, Γ =291 Κ. Source of materialThe mixture of H0CI3 · 6H2O (0.2 mmol) and W-p-acetamidobenzenesulfonylglycine acid (abglyH2, 0.6 mmol), was stirred into 15 ml aqueous solution. Then the pH was adjusted to 5 with 1 M NaOH. Then 3 ml ethanol solution of 4,4-bipyridine (0.2 mmol) was added. The reaction mixture was heated on a water bath for 10 hours at 70° and filtered. Colorless crystals were obtained after 20 days. DiscussionIn the past few years, the design and synthesis of metal organic materials have attracted increasing attention due to their potential applications in the field of optics, electronics, catalysis and magnetism [1][2][3][4][5][6]. Metal ions can be found as isolated clusters or chains which are connected to each other by the linkers. Organic carboxylates or N-donor ligands have been widely used in construction of coordination polymers containing transition metals. In contrast to the well-investigated transition metal system, the lanthanide coordination polymers have been less studied [7][8][9]. The lanthanide ions, with their high and variable coordination numbers, flexible coordination environments and luminescence properties, provide unique opportunities for discovery of unusual
