3-(Prop-2-yn-1-yloxy)phthalonitrile
In the title compound, C11H6N2O {systematic name: 3-(prop-2-yn-1-yl-oxy)benzene-1,2-dicarbo-nitrile}, the 14 non-H atoms are approximately coplanar (r.m.s. deviation = 0.051 Å) with the terminal ethyne group being syn with the adjacent cyano residue. In the crystal, centrosymmetric dimers are connected by pairs of C-H⋯N inter-actions and these are linked into a supra-molecular tape parallel to ...

In the title compound, C(21)H(18)Si, the coordination geometry around the Si atom is a slightly distorted tetra-hedron with C-Si-C angles in the range 106.05 (11) to 110.58 (10) ° and Si-C bond lengths in the range 1.855 (2) to 1.883 (3) Å. The alkyne C-C bond length is 1.167 (4) Å. The dihedral angles between the three phenyl rings are 63.89 (7), 86.38 (7) and 70.51 (8)°. In the crystal, mol-e...

In the title mol-ecule, C10H8O2, all non-H atoms are essentailly coplanar (r.m.s. deviation = 0.0192 Å), indicating an effective conjugation of the carbonyl group, the benzene ring and the lone pair of the propyn-yloxy O atom. In the crystal, π-π stacking inter-actions [centroid-centroid distance = 3.5585 (15) Å] connect mol-ecules into inversion dimers which are linked by Csp-H⋯O=C hydrogen bo...
متن کاملResearch Article Global Asymptotic Behavior of yn+1=(pyn+yn-1)/(r+qyn+yn-1)
We investigate the global stability character of the equilibrium points and the period-two solutions of yn+1 = (pyn + yn−1)/(r + qyn + yn−1), n = 0,1, . . . , with positive parameters and nonnegative initial conditions. We show that every solution of the equation in the title converges to either the zero equilibrium, the positive equilibrium, or the period-two solution, for all values of parame...

The mol-ecular structure of the title compound, C(18)H(16)O(3), exhibits a new R(2)-C(COOMe)(OCH(2)CCH) group. The C-O-C-C torsion angle is 153.3 (1)°. The dihedral angles are 79.89 (5)° between phen-yl/phenyl planes, and 73.13 (5) and 79.05 (8)° for the two COOMe/phenyl plane pairs.
