Crystal structure of the co-crystalline adduct 1,3,6,8-tetra-aza-tri-cyclo-[4.4.1.1(3,8)]dodecane (TATD)-4-bromo-phenol (1/2).

ABSTRACT: The structure of the 1:2 co-crystalline adduct C8H16N4·2C6H5BrO, (I), from the solid-state reaction of 1,3,6,8-tetra-aza-tri-cyclo-[4.4.1.1(3,8)]dodecane (TATD) and 4-bromo-phenol, has been determined. The asymmetric unit of the title co-crystalline adduct comprises a half mol-ecule of aminal cage polyamine plus a 4-bromo-phenol mol-ecule. A twofold rotation axis generates the other half of the adduct. The primary inter-species association in the title compound is through two inter-molecular O-H?N hydrogen bonds. In the crystal, the adducts are linked by weak non-conventional C-H?O and C-H?Br hydrogen bonds, giving a two-dimensional supra-molecular structure parallel to the bc plane.

Crystal structure of the co-crystalline adduct 1,3,6,8-tetra-aza-tri-cyclo-[4.4.1.1(3,8)]dodecane (TATD)-4-chloro-3,5-di-methyl-phenol (1/1).

Project description:In the crystal of the title co-crystalline adduct, C8H16N4·C8H9ClO, (I), prepared by solid-state reaction, the mol-ecules are linked by inter-molecular O-H⋯N hydrogen bonds, forming a D motif. The aza-adamantane structure in (I) is slightly distorted, with N-CH2-CH2-N torsion angles of 10.4 (3) and -9.0 (3)°. These values differ slightly from the corresponding torsion angles in the free aminal cage (0.0°) and in related co-crystalline adducts, which are not far from a planar geometry and consistent with a D 2d mol-ecular symmetry in the tetra-aza-tri-cyclo structure. The structures also differ in that there is a slight elongation of the N-C bond lengths about the N atom that accepts the hydrogen bond in (I) compared with the other N-C bond lengths. In the crystal, the two mol-ecules are not only linked by a classical O-H⋯N hydrogen bond but are further connected by weak C-H⋯π inter-actions, forming a two-dimensional supra-molecular network parallel to the bc plane.

Redetermination of 1,3,6,8-tetra-aza-tri-cyclo-[4.4.1.1(3,8)]dodeca-ne.

Project description:The structure of the title compound, C8H16N4, which consists of four fused seven-membered rings, has been redetermined at 173 K. This redetermination corrects the orientation of two H atoms, which were located at unrealistic positions in the original room-temperature study [Murray-Rust (1974 ▶). J. Chem. Soc. Perkin Trans. 2, pp. 1136-1141]. The complete mol-ecule is generated by -42m symmetry, with one quarter of a mol-ecule [one N atom (site symmetry m), two C atoms (one with site symmetry m and the other with site symmetry 2) and two H atoms] in the asymmetric unit. No directional inter-actions beyond van der Waals contacts are apparent in the crystal structure.

Crystal structure of the 1:2 co-crystal of 1,3,6,8-tetra-aza-tri-cyclo-[4.3.1.13,8]undecane (TATU) and 4-chloro-phenol (1/2).

Project description:In the title compound, C7H14N4·2C6H5ClO, which crystallized with two crystallographically independent 4-chloro-phenol mol-ecules and one 1,3,6,8-tetra-aza-tri-cyclo-[4.3.1.13,8]undecane (TATU) mol-ecule in the asymmetric unit, the independent components are linked by two O-H⋯N hydrogen bonds. The hydrogen-bond acceptor sites are two non-equivalent N atoms from the aminal cage structure, and the tricyclic system distorts by changing the C-N bond lengths. In the crystal, these hydrogen-bonded aggregates are linked into chains along the c axis by C-H⋯N hydrogen bonds. The crystal structure also features C-H⋯π contacts.

Crystal structure of the 1,3,6,8-tetra-aza-tri-cyclo[4.3.1.1(3,8)]undecane (TATU)-4-nitro-phenol (1/2) adduct: the role of anomeric effect in the formation of a second hydrogen-bond inter-action.

Project description:In the title ternary co-crystalline adduct, C7H14N4·2C6H5NO3, mol-ecules are linked by two inter-molecular O-H?N hydrogen bonds, forming a tricomponent aggregates in the asymmetric unit. The hydrogen-bond formation to one of the N atoms is enough to induce structural stereoelectronic effects in the normal donor?acceptor direction. In the title adduct, the two independent nitro-phenol mol-ecules are essentially planar, with maximum deviations of 0.0157?(13) and 0.0039?(13)?Å. The dihedral angles between the planes of the nitro group and the attached benzene rings are 4.04?(17) and 5.79?(17)°. In the crystal, aggregates are connected by C-H?O hydrogen bonds, forming a supra-molecular dimer enclosing an R 6 (6)(32) ring motif. Additional C-H?O inter-molecular hydrogen-bonding inter-actions form a second supra-molecular inversion dimer with an R 2 (2)(10) motif. These units are linked via C-H?O and C-H?N hydrogen bonds, forming a three-dimensional network.

Mechanochemical synthesis and crystal structure of a 1:2 co-crystal of 1,3,6,8-tetra-aza-tri-cyclo[4.3.1.13,8]undecane (TATU) and 4-chloro-3,5-dimethyl-phenol.

Project description:Solvent-free treatment of 1,3,6,8-tetra-aza-tri-cyclo-[4.3.1.13,8]undecano (TATU) with 4-chloro-3,5-di-methyl-phenol led to the formation of the title co-crystal, C7H14N4·2C8H9ClO. The asymmetric unit contains one aminal cage mol-ecule and two phenol mol-ecules linked via two O-H⋯N hydrogen bonds. In the aminal cage, the N-CH2-CH2-N unit is slightly distorted from a syn periplanar geometry. Aromatic π-π stacking between the benzene rings from two different neighbouring phenol mol-ecules [centroid-centroid distance = 4.0570 (11) Å] consolidates the crystal packing.

Crystal structures of (1,4,7,10-tetra-aza-cyclo-dodecane-κ(4) N)bis-(tri-cyano-methanido-κN)nickel and (1,4,7,10-tetra-aza-cyclo-dodecane-κ(4) N)(tri-cyano-methanido-κN)copper tri-cyano-methanide.

Project description:The structures of two mononuclear transition-metal complexes with tri-cyano-methanide (tcm(-)) and 1,4,7,10-tetra-aza-cyclo-dodecane (cyclen) ligands, [Ni(C4N3)2(C8H20N4)], (I), and [Cu(C4N3)(C8H20N4)](C4N3), (II), are reported. In the neutral complex (I), the nickel cation is coordinated by one cyclen ligand and two monodentate N-bound tcm(-) anions in a distorted octa-hedral geometry. The tcm(-) ligands are mutually cis. The Cu(II) atom in (II) displays a distorted tetra-gonal-pyramidal geometry, with the four N-donor atoms of the cyclen ligand in the equatorial plane, and one tcm(-) anion bound through a single N atom in an axial site, forming a monocation. The second tcm(-) molecule acts as a counter-ion not directly coordinating to the copper cation. In both (I) and (II), extensive series of N-H⋯N and C-H⋯N hydrogen bonds generate three-dimensional network structures.

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) dichloride tetra-hydrate.

Project description:The crystal structure of the novel hydrated CuII salt, [Cu(L)(H2O)2]Cl2·4H2O (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 the [Cu(L)(H2O)2]2+ cation (completed by crystallographic inversion symmetry), one chloride anion and two lattice water mol-ecules. The copper(II) atom exists in a tetra-gonally distorted octa-hedral environment with the four N atoms of the macrocyclic ligand in equatorial and two O atoms from water mol-ecules in axial positions. The latter exhibit a long axial Cu-O bond length of 2.7866 (16) Å due to the Jahn-Teller distortion. The macrocyclic ring adopts a stable trans-III conformation with typical Cu-N bond lengths of 2.0240 (11) and 2.0441 (3) Å. The complex is stabilized by hydrogen bonds formed between the O atoms of coordinated water mol-ecules and the NH groups as donors, and chloride anions as acceptors. The chloride anions are further connected to the lattice water solvent molecules through O-H⋯Cl hydrogen bonds, giving rise to a three-dimensional network structure.

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.
