Crystal structure of 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane bis-(perchlorate) dichloride from synchrotron X-ray data.

ABSTRACT: The crystal structure of title salt, C14H36N4 4+·2ClO4 -·2Cl-, has been determined using synchrotron radiation at 220?K. The structure determination reveals that protonation has occurred at all four amine N atoms. The asymmetric unit contains one half-cation (completed by crystallographic inversion symmetry), one perchlorate anion and one chloride anion. A distortion of the perchlorate anion is due to its involvement in hydrogen-bonding inter-actions with the cations. The crystal structure is consolidated by inter-molecular hydrogen bonds involving the 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane N-H and C-H groups as donor groups, and the O atoms of the perchlorate and chloride anion as acceptor groups, giving rise to a three-dimensional network.

Crystal structure of 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane bis-[chlorido-chromate(VI)] dichloride from synchrotron X-ray data.

Project description:The crystal structure of title compound, (C14H36N4)[CrO3Cl]2Cl2, has been determined by synchrotron radiation X-ray crystallography at 220?K. The macrocyclic cation lies across a crystallographic inversion center and hence the asymmetric unit contains one half of the organic cation, one chloro-chromate anion and one chloride anion. Both the Cl- anion and chloro-chromate Cl atom are involved in hydrogen bonding. In the crystal, hydrogen bonds involving the 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane (TMC) N-H groups and C-H groups as donor groups and three O atoms of the chloro-chromate and the chloride anion as acceptor groups link the components, giving rise to a three-dimensional network.

Crystal structure of 1,4,8,11-tetra-azonia-cyclo-tetra-decane bis-(dichromate) monohydrate from synchrotron data.

Project description:The asymmetric unit of the hydrated title salt, (C10H28N4)[Cr2O7]2·H2O [C10H28N4 = H4(cyclam) = 1,4,8,11-tetra-azonia-cyclo-tetra-deca-ne], contains two half-cations (both completed by crystallographic inversion symmetry), two dichromate anions and one water mol-ecule. The two [CrO7]2- anions exhibit a nearly staggered conformation, with bridging angles of 133.37 (11) and 136.28 (12)°. The distortions of the dichromate anions are due to their participation in hydrogen-bonding inter-actions with the water mol-ecule and the cations. Inter-molecular hydrogen bonds involving the cyclam N-H groups and water O-H groups as donor groups, and the O atoms of the dichromate anions as acceptor groups give rise to a three-dimensional network.

Crystal structure of bis-[trans-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?(4) N)bis-(thio-cyanato-?N)chromium(III)] tetra-chlorido-zincate from synchrotron data.

Project description:The structure of the title compound, [Cr(NCS)2(cyclam)]2[ZnCl4] (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-decane, C10H24N4), has been determined from synchrotron data. The asymmetric unit contains two independent halves of the Cr(III) complex cations and half of a tetra-chlorido-zincate anion. In each complex cation, the Cr(III) atom is coordinated by the four N atoms of the cyclam ligand in the equatorial plane and by two N-bound NCS(-) anions in a trans axial arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry. The mean Cr-N(cyclam) and Cr-N(NCS) bond lengths are 2.065?(4) and 1.995?(6)?Å, respectively. The macrocyclic cyclam moieties adopt centrosymmetric trans-III configurations with six- and five-membered chelate rings in chair and gauche configurations, respectively. The [ZnCl4](2-) anion, which lies about a twofold rotation axis, has a slightly distorted tetra-hedral geometry. The crystal packing is stabilized by hydrogen-bonding inter-actions between the N-H groups of the cyclam ligands, the S atoms of the NCS(-) groups and the Cl(-) ligands of the anion.

Crystal structure of trans-di-chlorido-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?4 N)chromium(III) bis-(form-amide-?O)(1,4,8,11-tetra-aza-cyclo-tetra-decane-?4 N)chromium(III) bis-[tetra-chlorido-zincate(II)].

Project description:The structure of the title compound, [CrCl2(C10H24N4)][Cr(HCONH2)2(C10H24N4)][ZnCl4]2 (C10H24N4 = 1,4,8,11-tetra-aza-cyclo-tetra-decane, cyclam; HCONH2 = formamide, fa), has been determined from synchrotron X-ray data. The asymmetric unit contains two independent halves of the [CrCl2(cyclam)]+ and [Cr(fa)(cyclam)]3+ cations, and one tetra-chlorido-zincate anion. In each complex cation, the CrIII ion is coordinated by the four N atoms of the cyclam ligand in the equatorial plane and two Cl ligands or two O-bonded formamide mol-ecules in a trans axial arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry. The Cr-N(cyclam) bond lengths are in the range 2.061?(2) to 2.074?(2)?Å, while the Cr-Cl and Cr-O(fa) bond distances are 2.3194?(7) and 1.9953?(19)?Å, respectively. The macrocyclic cyclam moieties adopt the centrosymmetric trans-III conformation with six- and five-membered chelate rings in chair and gauche conformations. The crystal structure is stabilized by inter-molecular hydrogen bonds involving the NH or CH groups of cyclam and the NH2 group of coordinated formamide as donors, and Cl atoms of the ZnCl4 2- anion as acceptors.

Project description:The Zn(II) atom in the cation of the title salt, [Zn(C(2)H(3)O(2))(C(18)H(40)N(4))]ClO(4), is five-coordinated by the four N atoms of the macrocycle and the O atom of the monodentate acetate ligand. The N(4)O donor set is based on a trigonal bipyramid with two N atoms occupying axial positions [N-Zn-N = 170.89?(16)°]. The perchlorate anions are associated with the cations via N-H?O hydrogen bonds; intra-molecular N-H?O(acetate) inter-actions are also observed. The neutral aggregates are connected into an helical chain along the b axis via N-H?O(acetate) hydrogen bonds. The perchlorate anion was found to be disordered about a pseudo-threefold axis: the major component of the disorder had a site occupancy factor of 0.692?(11).

1,4,8,11-Tetra-azoniacyclo-tetra-decane tetra-chloridocobaltate(II) dichloride.

Project description:The asymmetric unit of the title compound, (C(10)H(28)N(4))[CoCl(4)]Cl(2), contains two half-mol-ecules of the macrocycle, which are both completed by crystallographic inversion symmetry. In the dianion, the Co(2+) cation is tetra-hedrally coordinated by four Cl atoms; the Co-Cl bond lengths correlate with the number of hydrogen bonds that the chloride ions accept. The crystal cohesion is supported by electrostatic inter-actions which, together with numerous N-H?Cl, N-H?(Cl,Cl) and C-H?Cl hydrogen bonds, lead to a three-dimensional network.

Project description:The Cu(II) atom in the title salt, [Cu(C(10)H(24)N(4))(H(2)O)(2)](C(8)H(7)O(2))(2)·H(2)O, is chelated by the four N atoms of the 1,4,8,11-tetra-aza-cyclo-tetra-decane (cyclam) ligand and is coordinated by two water mol-ecules in a Jahn-Teller-type of tetra-gonally distorted octa-hedral geometry. The cations, anions and lattice water mol-ecules are linked by N-H?O and O-H?O hydrogen bonds to form a layer structure parallel to (001).

Project description:In the crystal structure of the title dinuclear compound, [Ni(2)(C(4)H(4)O(5))(C(16)H(36)N(4))(2)](ClO(4))(2)·H(2)O, the bridg-ing di-car-box-yl-ate dianion O,O'-chelates to two Ni atoms, both of which are also chelated by the N-macrocylic ligand. The Ni atoms exhibit a distorted octa-hedral coordination. N-H?O and O-H?O hydrogen bonds link the cations and the uncoordinated water mol-ecules into a layer structure; the perchlorate anions occupy the space between adjacent layers, and are only weakly linked to the layers. One of the perchlorate anions is disordered over two sets of sites in a 3:2 ratio.
