In the title compound, C12H6N2O2·C2H5OH, the mol-ecule of the 1,10-phenanthroline-5,6-dione is approximately planar, with a maximum deviation of 0.051 (1) Å. In the crystal, mol-ecules are linked by O-H⋯N and weak C-H⋯O hydrogen bonds, forming supra-molecular chains propagating along [110]. π-π stacking inter-actions are observed between the pyridine rings of neighbouring chains, the centroid-c...

In the title compound, C14H12F2N2O2S, the dihedral angle between the aromatic rings is 70.23 (8)° and the S-N-N=C torsion angle is 172.11 (11)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into [100] C(4) chains, with adjacent mol-ecules in the chain related by translational symmetry. The chains are linked by weak C-H⋯F and C-H⋯O inter-actions, thereby forming a three-dimensional n...

In the title compound, C16H19NO3, the pyrrolidine ring is in a twist conformation. The dihedral angle between the di-hydro-furan ring [maximum deviation = 0.0016 (11) Å] and the phenyl ring is 47.22 (8)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming helical chains along the b-axis direction. The chains are further linked by C-H⋯π inter-actions to constitute a thre...

The asymmetric unit of the title compound, {(C(9)H(14)N)(3)[CdCl(5)]}(n), comprises three 2,4,6-trimethyl-aniline dications and one half of the [Cd(2)Cl(10)](6-) anion. The Cd atoms are each coordinated by six Cl atoms, with octa-hedra linked by bridging, apical Cl atoms, forming linear chains running parallel to the a axis. The trimethylanilinium cations form stacks between the chains of CdCl(...

In the title compound, C(20)H(14)N(4), all the non-H atoms are roughly coplanar with an r.m.s. deviation of 0.0776 Å. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, forming chains along the ([Formula: see text]). The chains are connected by inter-molecular C-H⋯N hydrogen bonds and π-π stacking inter-actions between inversion-related phenanthroline, imidazole and phenyl rings wit...

In the cation of the title compound, C(32)H(26)OP(+)·CF(3)O(3)S(-), the dihedral angle between the benzene rings of the biphenyl group is 42.37 (8)°. In the crystal, the cations and anions inter-act through inter-molecular C-H⋯O hydrogen bonds, forming chains parallel to the b axis. These chains are further linked by C-H⋯π stacking inter-actions into layers parallel to the bc plane.

Overproduction of immunoglobulin light chains leads to systemic amyloidosis, a lethal disease characterized by the formation of amyloid fibrils in patients' tissues. Excess light chains are in equilibrium between dimers and less stable monomers which can undergo irreversible aggregation to the amyloid state. The dimers therefore must disassociate into monomers prior to forming amyloid fibrils. ...

In the title compound, C20H17NO3 (alternative name: N-hy-droxy-9,10-dimethyl-9,10-ethano-anthracene-11,12-dicarboximide), the rigid ethano-anthracene-dicarboximide moiety has a roof-shaped geometry, the inter-planar angle between the two terminal phenyl rings being 124.9 (6)°. In the crystal, mol-ecules are linked via O-H⋯O hydrogen bonds, forming chains along [010]. C-H⋯O and C-H⋯π inter-actio...

In this paper, the competition between two supply chains and their elements is studied. Each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. Therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...

Scenarios, which constrain the behavior of agents, can be the interface between computer experts (agent system developers) and application designers (scenario writers), as well as the interface between scenario writers and agents. It raises a number of challenging issues to execute multi-agent scenarios: 1) How can scenario writers generate customized scenarios easily? 2) How can scenario write...
