(18-Crown-6-?O)(pyrazolato-?N,N')-potassium(I).

ABSTRACT: The asymmetric unit of the title compound, [K(C(3)H(3)N(2))(C(12)H(24)O(6))], is composed of a potassium cation bonded to the six O atoms of a crown ether mol-ecule and the two N atoms of a pyrazolate anion. The K?O distances range from 2.8416?(8) to 3.0025?(8)?Å, and the two K?N distances are 2.7441?(11) and 2.7654?(11)?Å. The K cation is displaced by 0.8437?(4)?Å from the best plane through the six O atoms. The latter plane is almost perpendicular to the plane of the pyrazolate ring [dihedral angle 83.93?(3)°].

(18-Crown-6)potassium(I) di-phenyl-stibate(-1).

Project description:Red crystals of the title salt, [K(C12H24O6)][Sb(C6H5)2], were obtained by the reaction of SbPh3, KSnBi and 18-crown-6 in liquid ammonia. The asymmetric unit contains one half of a [K(18-crown-6)](+) cation and one half of an SbPh2 (-) anion, with the central element lying on a twofold axis and a centre of inversion, respectively. In the crystal structure, the sequestered potassium cations show weak inter-actions with the ?-electrons of the phenyl groups of the SbPh2 (-) anion [shortest K?C distances = 3.190?(2) and 3.441?(2)?Å], leading to one-dimensional strands along the crystallographic c axis. These strands are aligned in a pseudo-hexa-gonal packing perpendicular to the ab plane.

Crystal structures of two solvates of (18-crown-6)potassium acetate.

Project description:The crystal and mol-ecular strutures of two solvated forms of [K(18c6)]OAc (18c6 = 18-crown-6 = 1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane and OAc = acetate) were determined by single-crystal X-ray diffraction, namely (acetato-?2O,O')(1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane-?6O)potassium dihydrate, [K(CH3COO)(C12H24O6)]·2H2O (1) and (acetato-?2O,O')aqua-(1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane-?6O)potassium acetic acid monosolvate [K(CH3COO)(C12H24O6)(H2O)]·CH3COOH (2). In both compounds, the acetate anion is bonded to the potassium ion in a chelating fashion and the metal atom is consequently slightly displaced from the O6 plane of the crown ether. In the crystals, O-H?O hydrogen bonds lead to a polymeric ladder structure in the dihydrate 1, while the acetic acid hydrate 2 features inversion dimers.

In each [Cu(NCS)(3)](2-) anion, the Cu(I) atom is coordinated by three N atoms of thio-cyanate ligands in a trigonal-planar coordination geometry. Each [Cu(NCS)(3)](2-) anion bridges two [K(benzene-18-crown-6)](+) cations, with K-S distances of 3.317?(3) and 3.198?(3)?Å, and two [K(benzene-18-crown-6)](+) cations are linked across a crystallographic centre of inversion, with K-O distances of 2.903?(5)?Å.

(18-Crown-6)potassium [(1,2,5,6-?)-cyclo-octa-1,5-diene][(1,2,3,4-?)-naph-tha-lene]-ferrate(-I).

Project description:The title salt, [K(C(12)H(24)O(6))][Fe(C(8)H(12))(C(10)H(8))], is the only known naphthalene complex containing iron in a formally negative oxidation state. Each (naphthalene)(1,5-cod)ferrate(-I) anion is in contact with one (18-crown-6)potassium cation via K?C contacts to the outer four carbon atoms of the naphthalene ligand (cod = 1,5-cyclo-octa-diene, 18-crown-6 = 1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne). When using the midpoints of the coordinating olefin bonds, the overall geometry of the coordination sphere around iron can be best described as distorted tetra-hedral. The naphthalene fold angle between the plane of the iron-coordinating butadiene unit and the plane containing the exo-benzene moiety is 19.2?(1)°.

A one-dimensional polymeric cobalt(III)-potassium complex with 18-crown-6, cyanide and porphyrinate ligands.

Project description:The reaction of Co(II)(TpivPP) {TpivPP is the dianion of 5,10,15,20-tetra-kis-[2-(2,2-di-methyl-propanamido)-phen-yl]por-ph-yrin} with an excess of KCN salts and an excess of the 18-crown-6 in chloro-benzene leads to the polymeric title compound catena-poly[[dicyanido-2κ(2) C-(1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane-1κ(6) O){μ3-(2α,2β)-5,10,15,20-tetra-kis-[2-(2,2-di-methyl-propanamido)-phen-yl]porphyrinato-1κO (5):2κ(4) N,N',N'',N''':1'κO (15)}cobalt(III)potassium] dihydrate], {[CoK(CN)2(C12H24O6)(C64H64N8O4]·2H2O} n . The Co(III) ion lies on an inversion center, and the asymmetric unit contains one half of a [Co(III)(2α,2β-TpivPP)(CN)2](-) ion complex and one half of a [K(18-C-6](+) counter-ion (18-C-6 is 1,4,7,10,13,16-hexa-oxa-cyclo-octa-deca-ne), where the K(I) ion lies on an inversion center. The Co(III) ion is hexa-coordinated by two C-bonded axial cyanide ligands and the four pyrrole N atoms of the porphyrin ligand. The K(I) ion is chelated by the six O atoms of the 18-crown-6 mol-ecule and is further coordinated by two O atoms of pivalamido groups of the porphyrin ligands, leading to the formation of polymeric chains running along [011]. In the crystal, the polymeric chains and the lattice water mol-ecules are linked by N-H⋯O and O-H⋯N hydrogen bonds, as well as weak C-H⋯O, O-H⋯π and C-H⋯π inter-actions into a three-dimensional supra-molecular architecture.

Crystal structure of di-aqua-[5,10,15,20-tetra-kis-(4-meth-oxy-phen-yl)porphyrinato-?(4) N]iron(III) di-aqua-(18-crown-6)potassium bis-(tri-fluoro-methane-sulfonate)-18-crown-6 (1/2).

Project description:In the title compound, [Fe(III)(C48H36N4O2)(H2O)2][K(C12H24O6)(H2O)2](SO3CF3)2·2C12H24O6, the Fe(III) atom is situated on an inversion centre and is octa-hedrally coordin-ated by four pyrrole N atoms of the deprotenated 5,10,15,20-tetra-kis-(4-meth-oxy-phen-yl)porphyrinate ligand and two water mol-ecules. The average equatorial Fe-N(pyrrole) bond length [2.043?(6)?Å] is consistent with a high-spin (S = 5/2) iron(III) metalloporphyrin derivative. The K(+) cation, which also lies on an inversion centre, is chelated by the six O atoms of one 18-crown-6 mol-ecule and is additionally coordinated by two water mol-ecules in a distorted hexa-gonal-bipyramidal geometry. In the crystal, the cations, anions and one non-coordinating 18-crown-6 mol-ecule are linked by classical O-H?O hydrogen bonds and non-conventional C-H?O hydrogen bonds, leading to a one-dimensional supra-molecular architecture along [10-1]. The crystal packing is further stabilized by weak C-H?? inter-actions involving pyrrole and phenyl rings of the porphyrins, as well as weak C-H?F contacts involving the (SO3CF3)(-) counter-ion and the 18-crown-6 mol-ecules.

Triaqua-chlorido(18-crown-6)barium chloride.

Project description:In the title compound, [BaCl(C(12)H(24)O(6))(H(2)O)(3)]Cl, the Ba(II) atom, the coordinating and free Cl(-) anions, one coordinating water mol-ecule and two O atoms of an 18-crown-6 mol-ecule lie on a mirror plane. The environment of the ten-coordinate Ba(2+) ion is defined by one Cl atom, three water mol-ecules and six O atoms from the macrocyclic ether. The macrocycle adopts a conformation with an approximate D(3d) symmetry. In the crystal, O-H?Cl hydrogen bonds link the complex cations and Cl(-) anions into a two-dimensional network parallel to (010). An intra-molecular O-H?Cl hydrogen bond is also present.
