The title compound [In(H2ip)(pdc)(H2O)] (H3ip = 5-hydroxyisophthalic acid, H2pdc = pyridine-2,6-dicarboxylic acid) has been synthesized and characterized by single-crystal X-ray diffraction analysis. It crystallizes in monoclinic, space group P21/c with a = 13.830(8), b = 6.488(4), c = 17.632(10) , β = 92.510(10)°, C15H10InNO10, Mr = 479.06, V = 1580.6(15) 3, Z = 4, Dc = 2.013 g/cm3, F(000) = 944, μ = 1.557 mm-1, the final R = 0.0413 and wR = 0.0793 for 2950 observed reflections with I > 2σ(I). The In(III) ion is seven-coordinated in a slightly distorted penta-bipyramidal geometry. The mixed ligands connect the In(III) ions into 21 helical chains along the [010] direction, and the hydrogen bonds assemble the chains into a three-dimensional supramolecular network.
The reaction of 2,4,6-tris(2-pyridyl)-1,3,5-triazine(tptz) and K2PdCl4 in THF/H2O(10:1) results in the hydrolysis of tptz to bis(2-pyridylcarbonyl)amide anion(bpca),and affords complex Pd(bpca)Cl 1,which is the first example of Pd(Ⅱ)-promoted hydrolysis of ligands.Crystal data for 1:orthorhombic,space group Pbcn,a=12.0136(17),b=14.180(2),c=6.9747(11) ,V= 1188.2(3) 3,Z=4,Mr=368.06,Dc=2.058 g/cm3,F(000)=720,μ=1.786 mm-1,λ(MoKα)= 0.71073 ,T=293(2) K,2θmax=54.9o,GOOF=1.085,the final R=0.0647 and wR=0.1051 for 1234 observed reflections with I > 2σ(I)(refinement on F2).Complex 1 is connected through hydrogen bonding to give a 2D network.And weak Pd…Pd interactions are also found between adjacent molecules with the distance of 3.6074(5) ,so the complex is further extended into a 3D supramolecular structure.Thermal gravity analysis(TGA) shows that 1 exhibits high thermal stability below 310 ℃.X-ray powder diffraction(XRD) and UV/Vis spectrum of 1 are also discussed.
A new bismuth compound Bi(Hsal)3(1,10-phenanthroline) (Hsal=O2CC6H4-2-OH) has been synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in the triclinic system, space group P1, with a=10.243(2), b=11.905(3), c=12.934(3), α=76.780(6), β=68.683(6), γ=80.930(7)o, V=1425.6(5)3, Dc=1.865 g/cm3, Mr=800.51, F(000)=780, μ= 6.247 mm-1, Z=2, R=0.0456 and wR=0.1131 for 5612 observed reflections (I > 2σ(I)). In this compound, three salicylate ligands coordinate to the Bi atom through the carboxylate groups to form a four-membered chelate ring, and phenanthroline ligand chelates the metal through two N atoms. The structure of the title compound manifests a possible coordination mode between bismuth subsalicylate and N atom containing amino acid in the biological system.

A mercury(Ⅱ) iodide complex with organosulfide [Hg(pymt)(pymtH)I] 1 (pymt = the anion of pyrimidine-2-thiolate) has been synthesized by slow evaporation of the solution at room temperature and structurally characterized by single-crystal X-ray diffraction. Basic ideas and data collected are given. X-ray diffraction analysis reveals that complex 1 is mononuclear. Crystallographic data: C8H7HgIN4S2, Mr = 550.79, monoclinic system, space group P21/c, a = 11.218(4), b = 9.551(3), c = 15.877(4) , β = 129.697(15)°, V = 1308.9(7) 3, Z = 4, Mr = 550.79, Dc = 2.795 g/cm3, F(000) = 992, μ(MoKα) = 14.415 mm-1, λ(MoKα) = 0.71073 , T = 293(2) K, 2θmax = 54.9o, GOOF = 1.053, the final R = 0.0310 and wR = 0.0742 for 2547 observed reflections with I > 2σ(I) (refinement on F2). Complex 1 is connected through hydrogen bonds to give a one-dimensional supramolecular chain structure. Furthermore, π-π interactions are also found between the pyrimidine rings with the center-to-center distances of 3.439(4) and 3.603(4) , so complex 1 expands the chains into a two-dimensional network.
