4,9,12,15-Tetra-oxa-3,5,8,10,14,16-hexa-aza-tetra-cyclo-[11.3.0.0.0]hexa-deca-1(16),2,5,7,10,13-hexaen-3-ium-3-olate monohydrate.

ABSTRACT: The organic mol-ecule in the title monohydrate, C(6)N(6)O(5)·H(2)O, presents an almost planar configuration, the greatest deviation from the least-squares plane through the atoms being 0.061 (1) Å for the O atom within the seven-membered ring. Each water H atom is bifurcated, one forming two O-H⋯N hydrogen bonds and the other forming O-H⋯N,O hydrogen bonds. The result of the hydrogen bonding is the formation of supra-molecular layers with a zigzag topology that stack along [001].

Crystal structures of two nickel(II) macrocyclic salts: (5,7,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)nickel(II) bis-(perchlorate) monohydrate and (5,7,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)nickel(II) dibromide trihydrate.

Project description:The crystal structure of the Ni-14 macrocycle salt, (5,7,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)nickel(II) bis-(perchlorate) hemihydrate, [Ni(C16H36N4)]2(ClO4)4·H2O, contains two different diasteriomeric macrocyclic cations in the asymmetric unit, one with two NH protons on each side of the cation (Ia), and the other with all four NH protons on the same side (Ib). The crystal structure of the bromide trihydrate salt of the same Ni-14 macrocyclic cation, namely (5,7,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)nickel(II) dibromide trihydrate, [Ni(C16H36N4)]Br2·3H2O (II), contains only the same diastereomer as Ib, with the four N-H bonds on the same side. The geometry around the Ni atom differs slightly between the two diastereomeric cations, as the mean Ni-N distance in Ia is 1.952 (2) Å, while that for Ib and II is 1.928 (2) Å. The hexa-methyl substitution in all three macrocyclic cations has the two dimethyl-substituted C atoms cis to one another, different from the trans 5,5,7,12,12,14-hexa-methyl Ni-14 cations found in all but one of the many published crystal structures of hexa-methyl Ni-14 macrocycles. In each of the two crystal structures, the anions, water mol-ecules, and N-H protons of the macrocyclic cations form extensive hydrogen-bonded zigzag chains propagating along [001] in I and [010] in II.

Bromido(meso-5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-1,7-diene)copper(II) bromide dihydrate.

Project description:There are two formula units (Z' = 2) in the asymmmetric unit of the title compound, [CuBr(C(16)H(32)N(4))]Br·2H(2)O. The title crystal consists of two [Cu(C(16)H(32)N(4))](2+) cations, two Br(-) anions and four uncoordinated water mol-ecules. The metal atom is five-coordinate square pyramidal, with a long apical Cu-Br bond [2.9734 (11) and 2.9229 (11) Å in the two cations]. The two cations form a loosely associated dimer through the formation of hydrogen bonds between both N-H and O-H and Br(-). In addition, there is a network of N-H⋯Br, O-H⋯Br and N-H⋯O hydrogen bonds, leading to the formation of a chain structure.

The hy-droxy and amino groups are syn, and the hy-droxy H atom forms an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules assemble via C-H⋯O and C-H⋯π inter-actions, consolidating a three-dimensional architecture.

Diaqua-(1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)nickel(II) fumarate tetra-hydrate.

Project description:The asymmetric unit of the title complex salt, [Ni(C(10)H(24)N(4))(H(2)O)(2)](C(4)H(2)O(4))·4H(2)O, comprises half of a nickel(II) complex dication, half of a fumarate dianion and two water mol-ecules. Both the Ni(II) cation and fumarate anion lie on a crystallographic inversion center. The Ni(II) ion in the cyclam complex is six-coordinated within a distorted N(4)O(2) octa-hedral geometry, with the four cyclam N atoms in the equatorial plane and the two water mol-ecules in apical positions. The six-membered metalla ring adopts a chair conformation, whereas the five-membered ring exists in a twisted form. In the crystal packing, inter-molecular O-H⋯O hydrogen bonds between the water molecules and the carboxyl groups of the fumarate anions lead to the formation of layers with R(4) (2)(8) ring motifs. Ni(II) complex cations are sandwiched between two such layers, being held in place by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, consolidating a three-dimensional network.

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.

Crystal structure of trans-di-aqua-(3,10-dimethyl-1,3,5,8,10,12-hexa-aza-cyclo-tetra-deca-ne)copper(II) pamoate.

Project description:The asymmetric unit of the title compound, trans-di-aqua-(3,10-dimethyl-1,3,5,8,10,12-hexa-aza-cyclo-tetra-decane-κ4 N 1,N 5,N 8,N 12)copper(II) 4,4'-methyl-ene-bis(3-hy-droxy-naphthalene-2-carboxyl-ate), [Cu(C10H26N6)(H2O)2](C23H14O6) {[Cu(L)(H2O)2](pam), where L = 3,10-dimethyl-1,3,5,8,10,12-hexa-aza-cyclo-tetra-decane and pam = dianion of pamoic acid} consists of two independent halves of the [Cu(L)(H2O)2]2+ cation and one di-carboxyl-ate anion. The CuII atoms, lying on inversion centres, are coordinated by the four secondary N atoms of the macrocyclic ligands and the mutually trans O atoms of the water mol-ecules in a tetra-gonally elongated octa-hedral geometry. The average equatorial Cu-N bond length is significantly shorter than the average axial Cu-O bond length [2.007 (10) and 2.486 (18) Å, respectively]. The macrocyclic ligand in the complex cations adopts the most energetically stable trans-III conformation. The complex cations and anions are connected via hydrogen-bonding inter-actions between the N-H groups of the macrocycles and the O-H groups of coordinated water mol-ecules as the proton donors and the O atoms of the carboxyl-ate as the proton acceptors into layers lying parallel to the (11) plane.

μ-Actetato-1:2κO:O'-tribromido-2κBr-(5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-1,7-diene-1κN)dizinc(II).

Project description:In the title compound, [Zn(2)Br(3)(CH(3)COO)(C(16)H(32)N(4))], one Zn(II) atom has a distorted square-planar coordination formed by the four macrocyclic N atoms with an acetate O atom in the apical position and the other Zn(II) atom has a tetra-hedral coordination environment formed by three Br atoms and one O acetate atom. The two Zn(II) atoms are linked by an acetate bridge. In the crystal, mol-ecules are linked into centrosymmetric dimers with graph-set motifs R(2) (2)(16) by an N-H⋯Br inter-action. The mol-ecular configuration is stabilized by an intra-molecular N-H⋯Br hydrogen bond.

Project description:The title compound, C(14)H(21)NO(4), has been synthesized from o-dihydroxy-benzene by a three-step reaction. There are two chemically equal but crystallographically independent mol-ecules in the asymmetric unit. The crystal packing is governed by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming an infinite network.
