Bis(ethylenediamine-κ2N,N′)bis(methanol-κO)copper(II) benzene-1,4-dicarboxylate methanol disolvate

In the cation of the title compound, [Cu(C2H8N2)2(CH3OH)2](C8H4O4)·2CH3OH, the CuII atom lies on an inversion centre. The four N atoms of two ethyl­enediamine ligands around the CuII atom form the equatorial plane, while two methanol O atoms in the axial positions complete a Jahn–Teller distorted octa­hedral coordination. The benzene-1,4-dicarboxyl­ate anion is centrosymmetric. In the crystal, C—H⋯O, N—H⋯O and O—H⋯O hydrogen bonds link the cations, the anions and the methanol solvent mol­ecules.

10-Hydroxybenzo[h]quinolin-1-ium tetrachlorido(pyridine-2-carboxylato-κ2 N,O)stannate(IV) methanol monosolvate

The reaction of 4-(dimethyl­amino)­pyridine, picolinic acid and stannic chloride yields the title monosolvated salt, (C13H10NO)[SnCl4(C6H4NO2)]·CH3OH. The SnIV atom is N,O-chelated by the picolinate ion in a cis-SnNOCl4 octa­hedral geometry. The cation is linked to the methanol solvent mol­ecule by an O—H⋯O hydrogen bond; the solvent mol­ecule itself is a hydrogen-bond donor to the uncoordinating carboxyl­ate O atom of the anion. The cations and anions are linked by weak N—H⋯Cl inter­actions, forming a chain running along the b axis.

In the crystal, the cations, anions, water and methanol mol­ecules are linked by O—H⋯O and N—H⋯O hydrogen bonds, forming a three-dimensional network.

(3β,18β,20β)-N-Ethoxycarbonylmethyl-3-nitrato-11-oxoolean-12-ene-29-carboxamide methanol monosolvate

The title compound, C34H52N2O7·CH4O, is the methanol solvate of a difunctionalized derivative of the therapeutic agent 18β-glycyrrhetinic acid, a penta­cyclic triterpene. The five six-membered rings of the glycyrrhetinic acid moiety show normal geometries, with four rings in chair conformations and the unsaturated ring in a half-chair conformation. This moiety is substituted by a nitrate ester group and an O-ethyl­glycine group. In the crystal, the nonsolvent mol­ecules are packed parallel to (010) in a herringbone fashion with the nitrato, ethyl­glycine and methanol-O atom being proximate. The methanol solvent mol­ecule is anchored via a donated O—H⋯Oac­yl and an accepted N—H⋯O hydrogen bond, giving rise to infinite zigzag chains of hydrogen bonds parallel to [100]. Two weak intermolecular C—H⋯O interactions to the methanol and to an acyl oxygen establish links along [100] and [010], respectively.

The dihedral angle between the two chelate rings is 82.92 (5)°. In the coordinated ligand, the phenol ring is twisted at 30.22 (9)° from the mean plane of the fluorene ring. In the crystal, O—H⋯O hydrogen bonds link the complex mol­ecules to the methanol solvent mol­ecules.

In the crystal, the hydrazone mol­ecules are linked via the methanol solvent mol­ecule through N—H⋯O and O—H⋯O hydrogen bonds, so forming chains propagating along the a-axis direction.

Organophosphine/phosphite‐stabilized silver(I) complexes bearing N‐hydroxysuccinimide ligand: synthesis, solid state structure and their potential use as MOCVD precursors

Six organophosphine/phosphite‐stabilized silver(I) N‐hydroxysuccinimide complexes of type [C4H4NO3Ag⋅Ln] (L = PPh3; n = 1, 2a; n = 2, 2b; L = P(OEt)3; n = 1, 2c; n = 2, 2 d; L = P(OMe)3; n = 1, 2e; n = 2, 2f) were prepared. These complexes were obtained in high yields and characterized by elemental analysis, 1H NMR, 13 C{1H} NMR and IR spectroscopy, respectively. The molecular structure of 2b has been determined by X‐ray single‐crystal analysis in which the silver atom is in a distorted tetrahedral geometry. An interstitial methanol solvent molecule is hydrogen bonded to the oxygen atom of N‐hydroxysuccinimide molecule. Complex 2f was used to deposit silver films by metal‐organic chemical vapor deposition (MOCVD) for the first time. The silver film obtained at 480 °C is dense and homogeneous, which is composed of many well‐isolated, granular particulates spreading all over the substrate surface.

2-(2-Carboxyethyl)-1,3-dioxoisoindoline-5,6-dicarboxylic acid methanol monosolvate

In the title compound, C13H9NO8·CH3OH, the main mol­ecule possesses three carb­oxy­lic acid groups, which are asymmetrically distributed around the mol­ecule core. This results in hydrogen-bonding motifs ranging from a chain to various rings. The combination of the chain motif together with a carb­oxy­lic dimer R 2 2(8) ring motif creates a ribbon of mol­ecules propagating along the c-axis direction. A second ribbon results from the combination of the chain motif together with a methanol solvent mol­ecule and carboxyl-containing R 4 4(12) ring motif. These two ribbons combine alternately, forming a hydrogen-bonded layer of mol­ecules parallel to (20).
