Poly[[(μ3-isonicotinato-κ3 O:O:N)(triphenyl­phosphine-κP)silver(I)] ethanol solvate]

In the crystal structure of {[Ag(C6H4NO2)(C18H15P)]·C2H6O}n, the 4-pyridylcarboxyl­ate ion binds to the phosphine-coordinated silver atoms through one of the two oxygen atoms of the carboxyl unit, and to a third phosphine-coordinate silver atom through the nitro­gen atom of the aromatic ring, giving a distorted tetra­hedral coordination at the metal atom. The μ 3-bridging mode leads to a layer motif; the disordered ethanol mol­ecules are linked to the free carboxyl oxygen atom by O—H⋯O hydrogen bonds

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

Di-μ2-methano­lato-bis­(μ-4-methyl-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazolido-κ2 N 1:N 2)di-μ3-oxido-tetra­kis­[dimethyl­tin(IV)]

The title distannoxane, [Sn4(CH3)8(C3H4N3S)2(CH3O)2O2], lies about a center of inversion; the tetra­nuclear mol­ecule features a three-rung-staircase Sn4O4 core in which the two crystallographically independent SnIV atoms are bridged by the triazolide group. The negatively charged N atom of the triazolide group binds to the terminal Sn atom at a shorter distance [Sn—N = 2.239 (2) Å] compared with the neutral N atom that binds to the central Sn atom [Sn← N = 2.757 (3) Å]. The oxide O atom is three-coordinate whereas the methano­late O atom is two-coordinate. The terminal Sn atom is five-coordinate in a cis-C3SnNO trigonal–bipyramidal environment, whereas the central Sn atom is six-coordinate in a C2SnNO3 skew-trapezoidal–bipyramidal geometry

Di-μ2-methano­lato-bis­(μ-4-methyl-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazolido-κ2 N 1:N 2)di-μ3-oxido-tetra­kis­[dibutyltin(IV)]

The asymmetric unit of the title distannoxane, [Sn4(C4H9)8(C3H4N3S)2(CH3O)2O2], contains two mol­ecules, each of which lies about an individual center of inversion. The tetra­nuclear mol­ecule features a three-rung-staircase Sn4O4 core in which two independent SnIV atoms are bridged by the triazolide group. The negatively charged N atom of the triazolide group binds to the terminal Sn atom at a shorter distance [Sn—N = 2.262 (3), 2.254 (3) Å] compared with the neutral N atom that binds to the central Sn atom[SnN = 2.617 (4); 2.830 (3) Å]. The oxide O atom is three-coordinate whereas the methano­late O atom is two-coordinate. The terminal Sn atom is five-coordinate in a cis-C3SnNO trigonal–bipyramidal environment, whereas the central Sn atom is six-coordinate in a C2SnNO3 skew-trapezoidal–bipyramidal geometry

8-Hy­droxy-2-methyl­quinolinium tetra­chlorido(quinolin-2-olato-κ2 N,O)stannate(IV) methanol disolvate

In the reaction of 8-hy­droxy­quinoline, 2-methyl-8-hy­droxy­quinoline and stannic chloride, the 2-methyl-8-hy­droxy­quinoline is protonated, yielding the disolvated title salt, (C10H10NO)[SnCl4(C9H6NO)]·2CH3OH. The SnIV atom in the anion is N,O-chelated by the hy­droxy­quinolinate in a cis-SnNOCl4 octa­hedral geometry. In the crystal, the cation, anion and solvent mol­ecules are linked by N—H⋯O, O—H⋯O and O—H⋯Cl hydrogen bonds, generating a three-dimensional network

Methyl­(phenyl)­bis­(quinoline-2-carbox­ylato-κ2 N,O)tin(IV) monohydrate

The SnIV atom in each of the two independent mol­ecules in the asymmetric unit of the title compound, [Sn(CH3)(C6H5)(C10H6NO2)2]·H2O, is N,O-chelated by two quinoline-2-carboxyl­ate ions; the dative Sn—N bonds are significantly longer than the covalent Sn—O bonds. The two O and two N atoms comprise a trapezoid, and the diorganotin skeleton is bent over the longer N—N edge [C—Sn—C = 144.2 (1) and 144.5 (1)° in the two independent mol­ecules]. The uncoordinated water mol­ecules serve to connect the skew-trapezoidal bipyramidal tin-bearing mol­ecules, generating a linear chain motif running along the ac diagonal. The crystal studied was a non-merohedral twin having a minor component of 33.2 (1)%

Dimeth­yl(4′-pyridyl-2,2′:6′,2′′-terpyridine-κ3 N 1,N 1′,N 1′′)bis(thio­cyanato-κN)tin(IV)

The Sn atom in the title compound, [Sn(CH3)2(NCS)2(C20H14N4)], is N,N′,N′′-chelated by the terpyridine part of the N-heterocycle. The Sn atom exists in a trans-C2SnN5 penta­gonal–bipyramidal geometry [C—Sn—C = 173.66 (8)°] with the methyl groups in axial and the N atoms in equatorial positions

The methyl groups are trans to each other in the octa­hedron surrounding the metal atom [C—Sn—C = 176.61 (12)°]
