Owing to the harsh natural environment and unsustainable production system,environmental vulnerability differs substantially among and within regions^([1]).Over the past 20 years,the most environmentally vulnerable countries lost over half of their economic growth potential^([2]).International trade is a double-edged sword for environmental *** the one hand,production occurs beyond countries’borders while associated environmental impacts are displaced away from the location of consumption.

The title compound {Cu2(pdc)2(4,4?-bipy)(H2O)3H2O}2 1 (H2pdc = pyridine-2,6- dicarboxylic acid, also known as dipicolinic acid; 4,4?-bipy = 4,4?-bipyridine) has been synthesized by the hydrothermal reaction and its structure was determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group Pi with a = 7.2278(3), b = 10.6259(4), c = 17.7614(6) ? a = 79.5990(10), = 83.6300(10), ? = 71.8280(10)o, V = 1272.60(8) ?, C48H44Cu4N8O24, Mr = 1371.07, Z = 1, Dc = 1.789 g/cm3, = 1.747 mm-1, F(000) = 696, R = 0.0397 and wR = 0.1137 for 3938 observed reflections (I > 2s(I)). There are two kinds of Cu coordination environments, and each central copper(II) atom is five-coordinated in a distorted square-based pyramidal coordination geo- metry. Four copper(II) atoms are linked by four pdc and two 4,4?-bipy ligands to form an annular rectangle structure. Extensive hydrogen-bonding interactions involving carboxylate O atoms as well as coordinated and free water molecules lead to the formation of a three-dimensional network struc- ture.

We investigated the hydrolysis of TiⅣ along with naturally abundant AlⅢ ions and reported the formation of a stable and semiconducting nanocluster. Interestingly, this compound exhibits an unusual odd-membered ring structure and also represents the largest Al-containing polyoxotitanium cluster(PTC) observed thus far. The presence of a shell of organic ligands as well as the incorporation of hetero-AlⅢ ions endowed the nanocluster with high air, thermal, and pH stabilities. The present compound exhibited a record photocatalytic hydrogen evolution of 402.88 μmol g–1 h–1 among PTC materials. This work not only paves the way towards stable PTC materials but also provides new insights into the design of novel photocatalysts.

The compound contains a six-coordinated copper（Ⅱ） center, which is surround by four N atoms of two phen ligands （Cu-N distances in the range of 1.997（2）- 2.225（2） A）, one sulfate O atom （Cu-O = 2.0037（17） A） and one water O atom （Cu-O（Sw） = 2.719（2） A,） in a distorted octahedral geometry. Extensive hydrogen-bonding interactions are involved in water molecules, ligated sulfate anions and fumaric acid molecules. In addition, π-π interactions via aromatic nitrogen-containing ligands are also discussed. The combination of non-covalent interactions leads to the formation of a 3-D network structure.

A series of carboxylate-substituted trinuclear molybdenum cluster compounds formulated as Mo 3S 4(DTP) 3(RCO 2)(L), where R=H, CH 3, C 2H 5, CH 2Cl, CCl 3, R 1C 6H 4 (R 1 is the group on the benzene ring of aromatic carboxylate), L=pyridine, CH 3CN, DMF, have been synthesized by the ligand substitution reaction. The dissociation of the loosely-coordinated ligand L from the cluster core was studied by 31P NMR. The dissociation process of L is related to the solvent, temperature, and acidity of carboxylate groups, so as to affect the solution structure and reactive properties of the cluster. The long-distance interaction between ligands RCO 2 and L is transported by Mo 3S 4 core.
