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.

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.

A procedure for the synthesis of the heteropolymetallic germanium(IV) and copper(II) complex with trihydroxyglutaric acid
(H5Thgl) [Cu(H2O)6][Ge(μ3-Thgl)2{Cu(H2O)2}2] · 2H2O (I) was developed and the complex was isolated for the first time in the solid state. The product was characterized by elemental
analysis, powder X-ray diffraction, thermogravimetry, and IR spectroscopy. Compound I was studied by X-ray crystallography. The crystals are monoclinic, a = 10.216(2)?, b = 12.272(3)?, c = 10.679(2)?, β = 93.13(3)°, V = 1336.9(5)?3, Z = 2, space group P21/n, R1 = 0.0261 for 3616 reflections with I > 2σ(I). Compound I is composed of bimetallic [Ge(μ3-Thgl)2{Cu(H2O)2}2]2− anions, [Cu(H2O)6]2+ cations, and water molecules of crystallization. In the centrosymmetric trinuclear complex anion, the Ge(1) atom is bound
by two fully deprotonated bridging ligands to two Cu atoms. The Ge(1) atom is coordinated at distorted octahedron vertices
by six hydroxyl oxygen atoms of two Thgl5− ligands (average Ge(1)-O distance is 1.8874(13)?). The Cu coordination polyhedron in the anion is an extended square pyramid
(4 + 1) formed by the bridging hydroxyl oxygen atom (Cu(1)-O(3), 2.0039(12) ?), two carboxyl oxygen atoms (average CU(1)-O
distance is 1.9674(14)?) of two Thgl5− ligands, and two water oxygen atoms in equatorial and axial positions (Cu(1)-O, 1.9761(13) and 2.3643(14)?, respectively).
In the centrosymmetric cation, the Cu coordination polyhedron is an extended square bipyramid (4 + 2). The equatorial Cu-O
bond length is 1.9428(14) ? (average), the axial Cu-O bond is elongated to 2.5151(14)?. The cations and anions are combined
by H-bonds. 相似文献

The chain coordination polymers [Na2(μ-H2O)(H2O)CB[5]]Cl2 · 6H2O (I), [Na3(μ-H2O)4(H2O)4(CNPy@CB[6])]Cl3 · 8H2O (II), and [Rb2(μ-H2O)2(CNPy@CB[6])]Cl2 · 8H2O (III) were prepared by heating (110°C) of a mixture of sodium or rubidium chloride, cucurbit[n]uril (CB[n], where n = 5, 6), 4-cyanopyridine, and water. According to X-ray diffraction data, binding of polynuclear cations with CB[n] in I–III occurs through coordination of the oxygen atoms of the cucurbit[n]uril portals to alkali metal atoms. Complexes I–III of the above composition isolated to the solid phase as supramolecular compounds with CB[n] were structurally characterized

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

At room temperature, a coordination polymer [Ni(btec)(H2O)4][Ni(imi)2(H2O)4]·2H2O was synthesized by reaction of NiCl2·6H2O, 1,2,4,5-benzenetetracarboxylic dianhydridc and imidazole in a water/THF solution. The structure was determined by X-ray diffraction crystal structure analysis. It crystallizes in triclinic P1 space group with the crystal cell parameters of a=0.67542 (2) nm, b=1.000 14 (1) nm, c=1.09088 (3) nm, α=74.140(2)°, β= 74.388(1)°, y=73.239(2)°, and V=0.664 09(3) nm3, Z=1. The crystal structure shows that Ni1 atom is coordinated by four water and two imidazole molecules, while Ni2 is coordinated by four water molecules and two carboxyl oxygen atoms. The 1,2,4,5-benzenetetracarboxylate ions bridge Ni2 coordination centers to form one-dimensional chain structure. Moreover, the chains are further linked together by hydrogen bonds to form a two-dimensional network. CCDC: 295873. 相似文献

Ba[Co(heida)2](HCO3)·2H2O crystals were grown (orthorhombic, a = 9.4491(5) Å, b = 10.9719(5) Å, c = 19.6077(9) Å, Z = 4, space group Pca21), and their structure was solved by X-ray diffraction. The Co atoms in the complex anion were coordinated by two N-(2-hydroxyethyl)iminodiacetate
(heida) ligands via the N atom and two O atoms of each ligand. The Ba atoms and the complex anions form “honeycomb” layers
linked via three O atoms. The “honeycombs” are additionally linked by their Ba atoms with the O atoms of the hydroxyethyl
groups. The Ba atoms are aligned within a layer and linked via the bridging HCO3 hydrocarbonate groups. The c.n. of Ba atoms is 10 (one water molecule; five O atoms of the complex anions, one from each
of the nearest neighbors; and four O atoms of the hydrocarbonate ions).

o). The Nd ions are nine-coordinated by one oxygen atom of coordinated water and eight oxygen atoms of sulfates. Compound I displays the layer structure constructed by linking Nd ions with three-linkage SO4 tetrahedra as the bridge (affording one coordinated vertex and coordinated edge). Compound II crystallizes in the monoclinic space group P21/c with unit cell data: a = 6.594(13) ?, b = 14.783(3) ?, c = 16.599(3) ?, β = 93.47(3)°, V = 1614.2(6) ?3, ρ

o). The Ho ions are eight-coordinated by two oxygen atoms of coordinated water and six oxygen atoms of sulfates. The straight
chain-like structure of II is attained by alternatively arranging HoO8 polyhedra and two-linkage SO4 tetrahedra (affording two coordinated vertices). The TG results indicate that the two compounds experience three weight losses
and lead to distinct residues: Nd2O3 for I and HoO(SO4)0.5 for II. 相似文献
