A new Pd nitrate complex KCs[Pd(NO3)4]·0.5H2O is synthetized. Its crystal structure contains isolated complex anions [Pd(NO3)4]2−, cations K+, Cs+, and crystallization water. Square-planar coordination around Pd is achieved by oxygen atoms of monodentate nitrate ligands.
The coordinated nitrate ligands are all oriented in the same way, in a “basket”-like arrangement. The coordination around
Pd is completed to 4+1 by forming Pd...Pd contacts of 3.564 ?.

The reaction of indium thiocyanate with bipyridine (4,4-Bipy) and urotropine (Ur) gave [H2(4,4′-Bipy)][In(H2O)2(NCS)4]2 (I) and [HUr]2[In(H2O)(NCS)5] · 2H2O (II), which were identified using elemental analysis, IR spectra, and thermogravimetric analysis. The thermal decomposition of
compound I and II ends at 650 and 640°C, respectively, and gives In2O3. X-Ray diffraction analysis of compound I showed that complex anions in the crystal form chains through O-H…S hydrogen bonds. The anion chains form a close packing
of columns with bipyridine cations located in the voids.

The complex [mer-In(H2O)3Cl3] · 18C6 (I) was isolated from the InCl3-H2O-Solv-18C6 solutions (Solv = MeOH, EtOH, THF). The second crystallization from mother solutions resulted in [fac-In(H2O)3Cl3] · 18C6 · 2H2O (II). The crystal and molecular structures of isomers I, II were identified by the powder X-ray diffraction, IR, and X-ray
diffraction methods. Although complexes I, II have different compositions, they have the chain structure. The thermal decomposition
of complexes I, II was studied.

The structures of the crystals of Ba4[trans(N)-Co(Ida)2]3[cis-(N)-Co(Ida)2]2(ClO4)3 · 19.46H2O · 2CH3OH (I) and Ba[trans-(N)-Co(Ida)2]2 · 7H2O (II) (H2Ida is iminodiacetic acid) were determin by X-ray diffraction. The crystals of I containing two geometric isomers of the complex
anions [Co(Ida)2]− were obtained by a slow cooling of a hot solution, which contained initially only the cis-isomer. One Ba atom in I interacts with the trans-complex and with two cis-complexes to give a three-dimensional framework in crystal I. The positive charge of the last framework is compensated by
one more trans-complex and by the perchlorate ions, one of which acts as a bidentate ligand with respect to the Ba atom. The crystals of
II are built of the chains with the alternating Ba atoms and the trans-(N)-[Co(Ida)2]− anions. The other anions of the same structure are each “suspended” to the Ba atoms of the chain.

Tin coordination compounds [Sn(H2O)2Cl4] · 18C6 (I) and [Sn(H2O)2Cl4] · 18C6 · 2H2O (II) were synthesized and identified by IR spectroscopy, CH analysis, and X-ray powder diffraction. The crystal structures of
compounds I and II were determined. The crystals of I and II are orthorhombic; a = 16.871(1) ?, b = 7.7305(7) ?, c = 16.939(1) ?, Z = 4, space group Cmca for I; a = 14.206(2) ?, b = 20.376(3) ?, c = 8.319(1) A, Z = 4, space group Pna21 for II. The structural units of I and II are [Sn(H2O)2Cl4] · 18C6 complex molecules (in II, also water molecules of crystallization). The coordinated water molecules in I are trans and those in II are cis to each other. The structural units in the crystals of I and II are combined only by hydrogen bonds between water molecules and the crown-ether oxygen atoms with the formation of the chain
structure. Complex I was tested as the precursor of tin dioxide in a chemical vapor deposition (CVD) process. The morphology of the obtained film
was studied by atomic force microscopy (AFM) and scanning electron microscopy (SEM), and the composition was studied by laser

A novel binuclear praseodymium(III) complex with N-(2-propionyl)salicyloylhydrazone (C10H10N2O4, H3L) and p-hydroxybenzoic acid (C7H6O3, Phba) was prepared in a H2O-C2H5OH mixed solution, and the crystal structure of [Pr2(H2L)2(Phba)4(H2O)2] · 2H2O (I) was determined by X-ray single crystal diffractometry. Complex I crystallizes in the monoclinic system, space group P21/c, a = 1.1050(4), b = 1.9534(7), c = 1.2376(4) ?, β = 94.955(7)°, and Z = 4. In the structure each Pr3+ ion lies in a single capped square antiprism geometry coordinated by carboxyl O and acyl O atoms and azomethine N atom of
one ligand (H2L− form), which coordinates via the keto form, four carboxyl O atoms from two Phba, and O atoms of two water molecules. In each
molecule, two tridentate ligands were coordinated by the H2L− form, and each Pr3+ ion was chelated by the carboxyl group from Phba. The carboxyl groups of H2L− and other two Phba were coordinated via μ2-bridging form and bidentate bridging form, respectively. Complex I and ligands Phba and H3L were also searched for biological activity against Valsa mali by the growth rate method. The result showed that the inhibitory
rate of ligands Phba and H3L is better than complex I, especially Phba. 相似文献

analysis, X-ray photoelectron spectroscopy and single-crystal X-ray diffraction.

Two novel organic amine templated lanthanide sulfates, layer (H3DETA)[Nd(H2O)(SO4)3] (I) and chain-like (H3DETA)[Ho(H2O)2(SO4)3] (II), are hydrothermally synthesized by using diethylenetriamine (DETA) as template, and are structurally characterized by ICP,
elemental analysis, X-ray single-crystal diffraction, X-ray powder diffraction, IR, and TG. Compound I is monoclinic with space group P21 and data of unit cell: a = 6.6518(13), b = 10.373(2), c = 11.091(2) ?, β = 93.61(3)°, V = 763.7(3) ?3, ρ

The crystal data are as follows: a = 19.751(7), b = 35.573(12), c = 12.227(4) ?, V = 8591(5) ?3, Z = 16, space group Fdd2 ρc = 1.877 g/cm3, μ = 3.742 mm−1, F(000) = 4800, R = 0.0259, and wR = 0.0616 for 3218 observed reflections with I ≥ 2σ(I). For complex II, the Dy3+ ion is nine-coordinated by a Ttha ligand, yielding a pseudo-monocapped square antiprismatic conformation, and the complex
crystallizes in the monoclinic crystal system with space group P21/c. In addition, there is a free non-coordinate carboxyl group (-CH2COO−) in the [Dy(Ttha)]3− complex anion.
