Catena-Poly[ammonium (cadmium-tri-?-thio-cyanato-?S:N;?N:S)-1,4,10,13,16-hexa-oxa-cyclo-octa-decane (1/1)].

ABSTRACT: In the title compound, {(NH(4))[Cd(NCS)(3)]·C(12)H(24)O(6)}(n), the Cd(2+) ion, the ammonium cation, one of the SCN(-) ligands and the macrocycle are located on mirror planes. The thiocyanate anions act as bridging ligands between the Cd(II) ions, leading to a polymeric chain arrangement extending along [001] around a twofold screw axis. The ammonium ions are contained within the bowl of the macrocycle via extensive N-H?O hydrogen bonding.

?-Hexa-thio-metadiphosphato-bis-[(1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane-?(6) O)rubidium] aceto-nitrile disolvate.

Project description:The asymmetric unit of the title compound, [Rb2(P2S6)(C12H24O6)2]·2CH3CN, contains one half of an [Rb(18-crown-6)2]2[P2S6] unit and one aceto-nitrile solvent mol-ecule. The [Rb(18-crown-6)]2[P2S6] unit is completed by inversion symmetry. Its Rb(+) ion is situated near the centre of the macrocyclic cavity, but is displaced by 0.8972?(1)?Å from the O atoms of the crown in the direction of the [P2S6](2-) moiety. The overall coordination number of the cation is eight, defined by the six crown ether O atoms and by two terminal S atoms of the [P2S6](2-) anion. The hexa-thio-metadiphosphate anion is built up from two tetra-hedral PS4 units joined together by a common edge. The crystal structure is characterized by alternating layers of [Rb(18-crown-6)]2[P2S6] and aceto-nitrile solvent mol-ecules stacked along [010].

Project description:In the title compound, [Au(2)Ba(NCS)(4)(C(20)H(24)O(6))](n), the dithio--cyanato-aurate(I) anion adopts a dimeric structure with an Au⋯Au distance of 3.1109 (10) Å; both Au(I) atoms are also bonded to two S atoms. The Ba(II) ion adopts an irregular BaN(3)O(6) geometry, arising from the crown ether and three adjacent thio-cyanate N atoms; the extended structure of the complex can be described as a one-dimensional coordination polymer generated by the Ba⋯N inter-actions (two on the endo side and one on the exo side of the crown ether) running parallel to the b axis, with an anti-parallel arrangement of ribbons in the unit cell.

Diammonium tetra-kis-(iso-thio-cyanato)-zincate-1,4,10,13,16-hexa-oxa-cyclo-octa-deca-ne-water (1/2/1).

Project description:The title compound, (NH4)2[Zn(NCS)4]·2C12H24O6·H2O, the result of the reaction of ammonium thio-cyanate, 18-crown-6 and zinc(II) chloride in aqueous solution, exhibits an unusual supra-molecular structure. The Zn atom, two of the thio-cyanate chains and a water mol-ecule, disordered over two positions, lie on a mirror plane. The macrocycle adopts a conformation with approximate D 3d symmetry. The ammonium mol-ecules are contained within the bowl of the macrocycle via extensive N-H?O hydrogen bonds and the complex mol-ecules are linked via N-H?S hydrogen bonds, forming chains along the c-axis direction. The macrocycle is disordered over two positions [refined occupancy ratio = 0.666?(8):0.334?(8)]. The S atoms of two iso-thio-cyanate ligands are disordered within and about the mirror plane.

{[Eth-yl(pyridin-4-ylmeth-yl)carbamo-thio-yl]sulfanido-?(2) S,S'}(1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane-?(6) O)potassium.

Project description:The asymmetric unit of title salt co-crystal, [K(C9H11N2S2)(C12H24O6)], comprises a K(+) cation, an (-)S2CN(Et)py anion and a 18-crown-6 mol-ecule. Substantial delocalization of ?-electron density is evident in the di-thio-carbamate anion, as indicated by the equivalent C-S bond lengths. The K(+) cation sits within an O6S2 donor set lying 0.7506?(6)?Å out of the least-squares plane through the six O atoms (r.m.s. deviation = 0.1766?Å) of the 18-crown-6 mol-ecule with the two S atoms being on one side of this plane. Supra-molecular layers in the bc plane, sustained by C-H?O and C-H?? inter-actions, feature in the crystal packing.

cis-(1,4,8,11-Tetra-aza-cyclo-tetra-decane-κN (4))bis(-thio-cyanato-κN)chromium(III) thio-cyanate.

Project description:The crystal structure of [Cr(NCS)2(cyclam)]NCS (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-deca-ne, C10H24N4) has been determined by using synchrotron radiation at 98 K. The Cr(III) atom is in a slightly distorted octa-hedral environment with four N atoms of the macrocyclic ligand and two N-coordinated NCS(-) anions in cis positions. The average Cr-N(cyclam) and Cr-NCS bond lengths are 2.085 (5) and 1.996 (15) Å, respectively. In the crystal, the uncoordinating SCN(-) anion is hydrogen bonded through N-H⋯S and N-H⋯N inter-actions to neighbouring complex cations.

fac-(2-Amido-ethyl-?C,O)aqua-tri-chlorido-tin(IV) 1,4,7,10,13,16-hexa-oxacyclo-octa-decane (2/1).

Project description:The asymmetric unit of the title compound, [Sn(C(3)H(6)NO)Cl(3)(H(2)O)](2)·C(12)H(24)O(6), comprises a six-coordinate tin complex and a 18-crown-6 mol-ecule, the latter disposed about a centre of inversion. The tin atom is coordinated by three Cl atoms, that define a facial arrangement, a chelating C-,O- ligand, and a water mol-ecule. The resulting CCl(3)O(2) donor set defines a distorted octa-hedral geometry. The tin-bound aqua ligand forms O-H?O hydrogen bonds to the centrosymmetric 18-crown-6 mol-ecule, resulting in a tri-mol-ecular aggregate. These assemble into a supra-molecular chain along the a axis being connected by N-H?O hydrogen bonds.

Project description:In the title coordination polymer, [Hg(NCS)(2)(C(4)H(5)N(3))], the Hg(II) atom is four-coordinated by one aromatic N atom from a 2-amino-pyrimidine ligand, one S atom from a terminal thio-cyanate ligand, and one S atom and one N atom from a bridging thio-cyanate ligand. The crystal structure features polymeric chains running along the b axis which are stabilized by N-H?N hydrogen bonds.

Calcium disodium hexa-thio-diphosphate(IV) octa-hydrate.

Project description:Single crystals of the title compound, CaNa(2)(P(2)S(6))·8H(2)O, were obtained by adding calcium hydroxide to an aqueous solution of Na(4)(P(2)S(6))·6H(2)O. The structure is isotypic with that of its strontium analogue and consists of one Ca(2+) cation, two Na(+) cations, one-half of a centrosymmetric (P(2)S(6))(4-) anion with staggered confirmation and four water mol-ecules in the asymmetric unit. The crystal structure can be described as being built up from layers of cations and anions extending parallel to (101). Within a layer, each CaO(8) polyhedron is connected via edge-sharing to two NaO(4)S(2) octa-hedra and to one NaO(2)S(4) octa-edron. The NaO(4)S(2) octa-hedra are, in turn, linked with two (P(2)S(6))(4-) anions through common corners. Various O-H?S hydrogen-bonding inter-actions lead to cohesion of adjacent layers. The Ca(2+) and one Na(+) cation are situated on a twofold rotation axis and the second Na(+) cation is situated on an inversion centre.
