2,13-Dibenzyl-5,16-diethyl-2,6,13,17-tetra-aza-tricyclo-[16.4.0.0]docosan-2-ium nitrate.

ABSTRACT: One of the tertiary amine atoms has been protonated in the title salt, C(36)H(57)N(4) (+)·NO(3) (-). The four N atoms of the macrocycle are almost coplanar (r.m.s. deviation = 0.0053?Å), a result correlated with the formation of intra-molecular N-H?N and N-H?(N,N) hydrogen bonds. With respect to this plane, the benzyl groups lie to either side; a similar arrangement pertains for the cyclo-hexyl rings (each with a chair conformation). Helical supra-molecular chains are evident in the crystal, whereby alternating cations and anions are linked by C-H?O inter-actions. The chains are consolidated into supra-molecular arrays in the ab plane via C-H?? contacts involving both benzene rings.

3,14-Dimethyl-2,6,13,17-tetra-aza-tricyclo-[16.4.0.0]docosa-ne-(naphthalen-1-yl)methanol (1/2).

Project description:In the title co-crystal, C(20)H(40)N(4)·2C(11)H(10)O, the macrocycle is generated by a crystallographic inversion centre. The N atoms show a pyramidal coordination, and the cyclo-hexane ring that is fused to the 14-membered C(10)N(4) ring exists in a chair conformation, whereas the methyl substituent occupies an axial site. The (naphthalen-1-yl)methanol mol-ecule forms an O-H?N hydrogen bond to a cyclam N atom. The mean-square-plane passing through the 14-membered ring is approximately coplanar with the naphthalene fused-ring [dihedral angle = 6.6?(1)°].

{3,14-Dimethyl-2,6,13,17-tetra-aza-tricyclo-[16.4.0.0]docosane-κN,N',N'',N''')bis-(nitrato-κO)copper(II).

Project description:The Cu(II) atom in the title compound, [Cu(NO(3))(2)(C(20)H(40)N(4))], is N,N',N'',N'''-chelated by the macrocyclic ligand: the four N atoms form a square, above and below which are located the O atoms of the nitrate ions. The metal atom exists in a tetra-gonally distorted octa-hedron, on a special position of [Formula: see text] site symmetry. One of the amino groups is hydrogen bonded to an O atom of the nitrate ion. The other amino group is hydrogen bonded to O atom of an adjacent mol-ecule, generating a supra-molecular dimeric hydrogen-bonded dinuclear aggregate.

The structure determination reveals that protonation has occurred at diagonally opposite amine N atoms, and that the dication features intra-molecular N-H?N hydrogen bonds. In the crystal, a three-dimensional artchitecture is formed by O-H?Cl/N and N-H?Cl/O hydrogen bonds.

Project description:The crystal structure of the hydrated title salt, C22H48N4 4+·4Cl-·4H2O (C22H48N4 = H4 L = 3,14-diethyl-2,6,13,17-tetra-azoniatri-cyclo-[16.4.0.07,12]doco-sa-ne), 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 comprises one half of the macrocyclic cation (completed by crystallographic inversion symmetry), two chloride anions and two water mol-ecules. The macrocyclic ring of the tetra-cation adopts an exodentate (3,4,3,4)-D conformation. The crystal structure is stabilized by inter-molecular hydrogen bonds involving the macrocycle N-H groups and water O-H groups as donors, and the O atoms of the water mol-ecules and chloride anions as acceptors, giving rise to a three-dimensional network.

Crystal structure of 3,14-diethyl-2,13-di-aza-6,17-diazo-niatri-cyclo-[16.4.0.07,12]docosane dinitrate dihydrate from synchrotron X-ray data.

Project description:The crystal structure of title salt, C22H46N4 2+·2NO3 -·2H2O, has been determined using synchrotron radiation at 220 K. The structure determination reveals that protonation has occurred at diagonally opposite amine N atoms. The asymmetric unit contains half a centrosymmetric dication, one nitrate anion and one water mol-ecule. The mol-ecular dication, C22H46N4 2+, together with the nitrate anion and hydrate water mol-ecule are involved in an extensive range of hydrogen bonds. The mol-ecule is stabilized, as is the conformation of the dication, by forming inter-molecular N-H⋯O, O-H⋯O, together with intra-molecular N-H⋯N hydrogen bonds.

1-Hexyl-1,3,6,8-tetra-aza-tricyclo-[4.3.1.1]undecan-1-ium iodide.

Project description:In the title compound, C(13)H(27)N(4) (+)·I(-), the ethyl-ene bridge is distorted from the ideal D(2d) symmetry wherein an N-C-C-N planar bridge, around whose C-C bond the C-N and C-H bonds are exactly eclipsed, is disordered over two sites with equal occupancies. In both disorder components, the hexyl chain adopts an ideal all-trans conformation. In the crystal, adjacent ions are connected by C-H?I hydrogen bonds, forming ionic pairs that are further linked into chains along [101] via a second C-H?I inter-action.

Crystal structure of [2,13-bis-(acetamido)-5,16-dimethyl-2,6,13,17-tetra-aza-tri-cyclo-[16.4.0.07,12]docosane-κ4N]silver(II) dinitrate from synchrotron X-ray data.

Project description:The asymmetric unit of the title compound, [Ag(C24H46N6O2)](NO3)2 [C24H46N6O2 is (5,16-dimethyl-2,6,13,17-tetra-aza-tri-cyclo-[16.4.0.07,12]docosane-2,13-di-yl)diacetamide, L], consists of one independent half of the [Ag(C24H46N6O2)]2+ cation and one nitrate anion. The Ag atom, lying on an inversion centre, has a square-planar geometry and the complex adopts a stable trans-III conformation. Inter-estingly, the two O atoms of the pendant acetamide groups are not coordinated to the AgII ion. The longer distance of 2.227 (2) Å for Ag-N(tertiary) compared to 2.134 (2) Å for Ag-N(secondary) may be due to the effects of the attached acetamide group on the tertiary N atom. Two nitrate anions are very weakly bound to the AgII ion in the axial sites and are further connected to the ligand of the cation by N-H⋯O hydrogen bonds. The crystal packing is stabilized by hydrogen-bonding inter-actions among the N-H donor groups of the macrocycle and its actetamide substituents, and the O atoms of the nitrate anions and of an acetamide group as the acceptor atoms.

Crystal structure of di-aqua-(3,14-diethyl-2,6,13,17-tetra-aza-tri-cyclo-[16.4.0.07,12]docosa-ne)copper(II) (3,14-diethyl-2,6,13,17-tetra-aza-tri-cyclo[16.4.0.07,12]docosa-ne)copper(II) tetra-bromide dihydrate, [Cu(C22H44N4)(H2O)2][Cu(C22H44N4)]Br4·2H2O.

Project description:The crystal structure of the new double CuII complex salt, [Cu(L)(H2O)2][Cu(L)]Br4·2H2O (L = 3,14-diethyl-2,6,13,17-tetra-aza-tri-cyclo-[16.4.0.07,12]docosane, C22H44N4) has been determined using synchrotron radiation. The asymmetric unit contains one half of a [Cu(L)(H2O)2]2+ cation, one half of a [Cu(L)]2+ cation (both completed by crystallographic inversion symmetry), two bromide anions and one water solvent mol-ecule. The CuII atom in the first complex exists in a tetra-gonally distorted octa-hedral environment with the four N atoms of the macrocyclic ligand in equatorial and two aqua ligands in axial positions, whereas the CuII atom in the second complex exists in a square-planar environment defined by the four nitro-gen atoms of the macrocyclic ligand. The two macrocyclic rings adopt the most stable trans-III configuration with normal Cu-N bond lengths from 2.016 (3) to 2.055 (3) Å and an axial Cu-O bond length of 2.658 (4) Å. The crystal structure is stabilized by inter-molecular hydrogen bonds involving the macrocycle N-H or C-H groups and the O-H groups of water mol-ecules as donor groups, and the O atoms of water mol-ecules and bromide anions as acceptor groups, giving rise to a one-dimensional network extending parallel to [100].

Project description:The crystal structure of the title salt, C20H42N4 2+·2ClO4 -, has been determined using synchrotron radiation at 220 (2) K.
