16 , has been synthesized and explained as structure using some elemental analyses. FT-IR spectra, UV-Vis reflectance, magnetic measurements, thermal analysis and x-ray diffraction methods. The results showed that the unit cell of complex includes two molecules Ni II cation, four molecules salicylates as bridge and two molecules N,N-diethylnicotinamide ligands, also there is one molecule hydrated aqua. The compound crystallizes in the monoclinic space group P2 1 /c with the following unit-cell parameters: a = 13.6776(6) Å, b = 10.5238(3) Å, c = 21.8165(9), a = 90.00º, b = 126.546(3)º, g = 90.00º and Z = 2. The compound [Ni 2 (m-Sal) 4 (Dena) 2 ]H 2 O is a typical paddle-wheel complex structure. Two Ni II ions are bridged by four salicylate ligands (O2, O2 i , O3, O3 i , O5, O5 i , O6 and O6 i ) using a m-COOcoordination mode [symmetry code: (i) 1-x, 1-y, 1-z]. Each Ni II also coordinates to one nitrogen atom (N1 and N1 i ) from one N,N-diethylnicotinamide ligand molecule in the axial position. The complex has strong paramagnetic properties.

“…The Figure 1 displays that the eight-coordination Ca(II) ion forms a distorted square-antiprismatic CaO8 polyhedron. The 3,5-bis(4-pyridylmethoxy)benzoate ligand only uses its O atoms for coordinating, and its pyridyl nitrogens do not coordinate to Ca(II) ion, which is different from the Zn(II), Ni(II), and Cd(II) complex with 3,5-bis(4-pyridylmethoxy)benzoate ligand [21][22][23][24][25] Crystals …”

Abstract:A new 1D chained Ca(II) coordination polymer-namely, [CaL 2 (H 2 O) 2 ] n (HL = 3,5-bis(4-pyridylmethoxy)benzoic acid)-was synthesized though the reaction of Ca(ClO 4 ) 2 ·4H 2 O, 3,5-bis(4-pyridylmethoxy)benzoic acid and NaOH in H 2 O/CH 3 CH 2 OH (v:v = 1:2) solution. Its structure was determined by elemental analysis, infrared spectrum, and single-crystal XRD. Structural analyses show that each Ca(II) ion is eight-coordinated by six oxygen atoms of four 3,5-bis(4-pyridylmethoxy)benzoate ligands and two oxygen atoms of two coordinated H 2 O molecules to form a square-antiprismatic CaO 8 polyhedron. The Ca(II) complex displays a 1D chained structure constructed by the bridging effect of the bidentate carboxyl group of 3,5-bis(4-pyridylmethoxy)benzoate ligand. The catalytic activity of the Ca-complex was tested for the preparation of propargylamine in the A 3 coupling reaction.

“…In the past few decades, multifunctional organic ligands (e.g., N-or O-containing ligands) that have strong coordination abilities as well as providing the hydrogen bond acceptors/donors and p-conjugated systems have been widely used in the construction of supramolecular framework. [6,7] 5-(benzyloxy)isophthalic acid (H 2 L), as a dicarboxylate ligand synthesized before, not only can provides hydrogen bond acceptors/ donors and p-conjugated systems, but also can exhibits various conformations because of the flexible -CH 2 -O-spacer between the two phenyl rings. In this work, we exploited 5-(benzyloxy)isophthalic acid as primary ligand, and introduced phen as auxiliary ligand, which self-assemble with Cd (II) ions under hydrothermal conditions.…”

A new Cd(II) compound, namely [Cd 2 (phen) 2 (L) 2 ] n ¢n(H 2 O) (1 H 2 L D 5-(benzyloxy) isophthalic acid, phen D 1,10-phenanthroline), has been successfully synthesized under hydrothermal conditions. Single crystal X-ray analysis reveals that 1 features a onedimensional (1D) chain structure. Under the guidance of the hydrogen bond interactions, neighboring 1D chains inserted mutually, giving rise to the final 1D!2D interdigitated framework. Moreover, the luminescent property of 1 was also investigated in the solid state at room temperature.
