The charge-transfer complex 1-amino-anthraquinone-7,7',8,8'-tetra-cyano-quinodimethane (1/1).

ABSTRACT: The reaction of 1-amino-anthraquinone with 7,7',8,8'-tetra-cyano-quinodimethane yielded the title charge-transfer complex, C(14)H(9)NO(2)·C(12)H(4)N(4). The mol-ecules have maximum deviations from the mean planes through the non-H atoms of 0.0769?(14)?Å for an oxo O atom and 0.1175?(17)?Å for a cyano N atom, respectively. The dihedral angle between the two planes is 3.55?(3)°. In the crystal, mol-ecules are stacked into columns along the a-axis direction. Pairs of N-H?N and N-H?O inter-actions connect the mol-ecules perpendicular to the stacking direction. Additionally, an intra-molecular N-H?O hydrogen-bond inter-action is observed for 1-amino-anthraquinone.

7,7',8,8'-Tetra-meth-oxy-4,4'-dimethyl-3,3'-bicoumarin.

Project description:In the crystal structure, the title compound, C(24)H(22)O(8), lies on a twofold rotation axis and the asymmetric unit comprises one half-mol-ecule. The dihedral angle formed by the coumarin unit with the symmetry-related part is 74.78?(14)°. One of the meth-oxy groups attached to the coumarin unit is considerably twisted, making an angle of 87.17?(17)° with respect to the coumarin unit; the other is twisted by 0.66?(19)°. No classical hydrogen bonds are found in the sturcture; only a weak C-H?? inter-action and short intra-molecular O?O contacts [2.683?(2)-2.701?(2)?Å] are observed.

7,7',8,8'-Tetra-meth-oxy-4,4'-dimethyl-3,5'-bichromene-2,2'-dione.

Project description:In the title mol-ecule, C(24)H(22)O(8), the mean planes of the two coumarin units are inclined to each other at a dihedral angle of 79.93?(3)°. The attached meth-oxy groups form torsion angles of 7.65?(19) and 78.36?(14)° with respect to one coumarin unit, and angles of 9.01?(16) and 99.08?(11)° with respect to the other coumarin unit. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds connect pairs of mol-ecules to form dimers, generating R(2) (2)(16) and R(2) (2)(18) rings; the dimers are linked by further weak inter-molecular C-H?O hydrogen bonds, forming extended chains. Additional stabil-ization is provided by weak C-H?? inter-actions.

The 1:1 charge-transfer complex dibenzo-tetra-thia-fulvalene-pyromellitic dianhydride (DBTTF-PMDA).

Project description:The title charge-transfer (CT) complex, C10H2O6·C14H8S4, composed of donor dibenzo-tetra-thia-fulvalene (DBTTF) and acceptor pyromellitic dianhydride (PMDA), forms a mixed stacking pattern along the [-110] direction. The constituent mol-ecules occupy crystallographic inversion centers. They are nearly parallel and lie ca.3.41?Å from each other. The crystals exhibit a high degree of donor/acceptor overlap [88.20?(4)%] in the long direction of the DBTTF and PMDA mol-ecules as compared with 51.27?(5)% in the shortest direction of the mol-ecules.

The substituent phenyl ring is also disordered over two positions in a 0.59?(3):0.41?(3) ratio. There are no conventional hydrogen bonds joining the mol-ecules.

The packing of the mol-ecule shows weak bonded chains along a through C-H?O contacts and two intramolecular C-H?O interactions are also present.

Quantum ferroelectricity in charge-transfer complex crystals.

Project description:Quantum phase transition achieved by fine tuning the continuous phase transition down to zero kelvin is a challenge for solid state science. Critical phenomena distinct from the effects of thermal fluctuations can materialize when the electronic, structural or magnetic long-range order is perturbed by quantum fluctuations between degenerate ground states. Here we have developed chemically pure tetrahalo-p-benzoquinones of n iodine and 4-n bromine substituents (QBr4-nIn, n=0-4) to search for ferroelectric charge-transfer complexes with tetrathiafulvalene (TTF). Among them, TTF-QBr2I2 exhibits a ferroelectric neutral-ionic phase transition, which is continuously controlled over a wide temperature range from near-zero kelvin to room temperature under hydrostatic pressure. Quantum critical behaviour is accompanied by a much larger permittivity than those of other neutral-ionic transition compounds, such as well-known ferroelectric complex of TTF-QCl4 and quantum antiferroelectric of dimethyl-TTF-QBr4. By contrast, TTF-QBr3I complex, another member of this compound family, shows complete suppression of the ferroelectric spin-Peierls-type phase transition.
