“…Sr1 is coordinated by six carboxylate oxygen atoms and two hydroxyl oxygen atoms from six different L-tart ligands. The Cd-O distances and Sr-O distances are in the range of 2.201(7)-2.475(7) Å, 2.491(7)-2.660(6) Å, respectively, that are in the normal range [9]. Notably, the distances of Cd-O hydroxyl are longer than those of Cd-O carboxylate , which may be caused by the electronic effect of the hydroxyl hydrogen atom.…”

Source of materialAll reagents and solvents employed were commercially available andusedasreceivedwithoutfurther purification.The compound of 5-(4-carboxybenzyloxy)isophthalic acid (CIA) was synthesized by the procedure reported in the literature [1]. The mixture of CIA (0.05 g, 0.16 mmol), NaOH (0.02 g, 0.48 mmol) ,CaCl 2 × 2H 2 O(0.0263 g, 0.237 mmol) and 10 mL water was sealed in a 25 mL Teflon-lined stainless reactor and heated at 130°C for 72 h under autogeneous pressure. With cooling to room temperature, colourless crystals suitable forX-ray diffraction were obtained. Experimental detailsAllh ydrogena toms on carbonsw ereg enerated geometrically with d(C-H)=0.93-0.97 Å, and U iso (H) =1.2 U eq (C) for atoms of CH 2 groups and aromatic ring. Hydrogen atomsofthe water molecules were not localized. DiscussionRecently, the rational design and synthesis of novel coordination polymers have attracted intense attention in the field of supra-molecularchemistry and crystal engineering. We have seen arelated report [2], it has similarly used CIA as an organic ligand with the different metal ion Cd(II) to forma3D structure in which the coordination mode of CIA is not the sameasthat in this paper. In the asymmetric unit there are two crystallographically independent Ca(II) centers with different coordinations. The Ca1 is seven-coordinated by six Oatomsfrom four independent ligands CIA and one water molecule, showing apentagonal bipyramidal coordination. The bond lengths d(Ca-O) arei nt he range of 2.236(2)-2.5481(2) Å. Ca2 is six-coordinated by four Oa toms from four independent CIA ligands in the equatorial positions and two water molecules in the apical positions of an octahedron. The bond lengths d(Ca-O) are 2.3113(2) and 2.334(2) Å, respectively.EachCIA anion connects five Ca(II) (three Ca1and two Ca2)atoms to form alayer.The layers are linked by carboxylate groups of CIAa nionst og enerateat hree-dimensional framework.

“…Among the organic ligands, polycarboxylate ligands are the most commonly used ligands owing to their variable coordination modes and strong coordination abilities to transition metal ions. [5][6][7][8] In the past few decades, single metal carboxylate coordination polymers have been largely reported. [9][10][11] Comparatively speaking, heterometallic coordination polymers are rarely reported owing to the competition coordination of two different metal ions in the crystalline process.…”

A new heterometallic coordination polymer, namely [CuCa(tdc) 2 (DMA)(H 2 O) 2 ] n (1, H 2 tdc D 2,5-thiophenedicarboxylic acid, DMA D N, N-dimethylacetamide) has been solvothermally synthesized by the reactions of CuCl 2 , CaCl 2 , and H 2 tdc. X-ray structural analysis reveals that compound 1 features a 3D heterometallic framework based on one-dimensional{Ca-(COO) 2 -Cu-(COO) 2 -Ca} n -chains. Moreover, the luminescent properties of compound 1 and desolvated 1 were also investigated at room temperature.
