“…On considering the diphosphonic acids, 1-hydroxyethylidene-1,1-diphosphonic acid (CH 3 C(OH)(H 2 PO 3 ) 2 , hedpH 4 ) is a well-known diphosphonic acid, and the presence of the hydroxyl group in hedpH 4 makes an additional coordination possible in its metal complexes. A number of reports dealing with the crystal structural chemistry of metal diphosphonates having hedpH 4 as ligand were found in the literature. − The structures of these reported metal diphosphonates are mostly made up of metal-oxide polyhedra, layers, or chains. So far, only few alkaline-earth metal-hedp complexes have been reported, − and there is no systematic investigation on the reactions of alkaline-earth metal ions with hedpH 4 ligand without adding any template molecules or bases.…”

A series of new alkaline-earth metal diphosphonate frameworks were successfully synthesized under solvothermal reaction condition (160 °C, 3 d) using 1-hydroxyethylidene-1,1-diphosphonic acid (CH3C(OH)(H2PO3)2, hedpH4) as a diphosphonate building block and Mg(II), Ca(II), Sr(II), or Ba(II) ions as alkaline-earth metal ion centers in water, dimethylformamide, and/or EtOH media. These diphosphonate frameworks, (H2NMe2)4[Mg(hedpH2)3]·3H2O (1), (H2NMe2)2[Ca(hedpH2)2] (2), (H2NMe2)2[Sr3(hedpH2)4(H2O)2] (3), and [Ba3(hedpH2)3]·H2O (4) exhibited interesting structural topologies (zero-, one-, two-, and three-dimensional (0D, 1D, 2D, and 3D, respectively)), which are mainly depending on the metal ions and the solvents used in the synthesis. The single-crystal analysis of these newly synthesized compounds revealed that 1 was a 0D molecule, 2 has 1D chains, 3 was a 3D molecule, and 4 has 2D layers. All compounds were further characterized using thermogravimetric analysis, solid-state (31)P NMR, powder X-ray diffraction analysis, UV-vis spectra, and infrared spectroscopy. In addition, Eu(III)- and Tb(III)-doped compounds of 1-4, namely, (H2NMe2)4[Ln(x)Mg(1-x)(hedpH2)2(hedpH(2-x))]·3H2O (1Ln), (H2NMe2)2[Ln(x)Ca(1-x)(hedpH2)(hedpH(2-x))] (2Ln), (H2NMe2)2[Ln(x)Sr(3-x)(hedpH2)3(hedpH(2-x))(H2O)2] (3Ln), and [Ln(x)Ba(3-x)(hedpH2)2(hedpH(2-x))]·H2O (4Ln) (where Ln = Eu, Tb), were synthesized, and their photoluminescence properties were studied. The quantum yield of 1Eu-4Eu was measured with reference to commercial red phosphor, Y2O2S:Eu(3+) (YE), and the quantum yield of terbium-doped compounds 1Tb-4Tb was measured with reference to commercial green-emitting phosphor CeMgAl10O17:Tb(3+). Interestingly, the compound 2Eu showed very high quantum yield of 92.2%, which is better than that of the reference commercial red phosphor, YE (90.8%).

“…In the case of strontium, four layered Sr phosphonates have previously been structurally characterized. [9][10][11][12] In addition to these layered compounds, monomeric, 13 dimeric 14 and one-dimensional 15 Sr bisphosphonate structures and the threedimensional structure of Sr amino-tris(methylenephosphonic acid) 16 have been reported. All Ba phosphonates reported so far are polymeric materials.…”

4 H 8 ) 2 (H 2 O) 3.5 ] n (3), were prepared and structurally characterized in a study of the complexing properties of amide ester derivatives of (dichloromethylene)bisphosphonic acid, and their crystal structures were determined. All three compounds are coordination polymers. Compounds 1 and 2 consist of 1D chains. In 1, the chains contain two independent octahedral Mg atoms in special positions, connected by L 1 ligands, L 1 ¼ (Cl 2 CP 2 O 5 MeNC 4 H 8 O) 2À . In 2, the seven-coordinated Ba 2+ cations are connected to polymeric chains by L 1 ligands, and the metal atom is coordinated by five O atoms of three different L 1 ligands. The coordination polyhedron around the Ba 2+ cation is a distorted monocapped trigonal prism. In 3, the two-dimensional framework is built up from one-dimensional chains containing two independent seven-coordinated Sr atoms connected by two crystallographically independent L 2 ligands, L 2 ¼ (Cl 2 CP 2 O 5 MeNC 4 H 8 ) 2À . The coordination polyhedron around the Sr 2+ cations is a distorted monocapped trigonal prism. In 3 the chains are connected into a layered structure through the Sr(1) atoms, while in compounds 1 and 2 a layer-like construction is formed through hydrogen bonds.
