5-Bromo-3-(4-fluorophenylsulfinyl)-2,7-dimethyl-1-benzofuran
In the title compound, C(16)H(12)BrFO(2)S, the 4-fluoro-phenyl ring makes a dihedral angle of 83.29 (5)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds.

In the title compound, C(16)H(12)BrFO(3)S, the 4-fluoro-phenyl ring makes a dihedral angle of 72.35 (5)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked into [010] chains via two different inversion-generated pairs of C-H⋯O hydrogen bonds. The crystal structure also exhibits slipped π-π inter-actions between the benzene ring...

In the title compound, C17H15BrO2S, the 4-methyl-benzene ring makes a dihedral angle of 89.01 (7)° with the mean plane [r.m.s. deviation = 0.013 (2) Å] of the benzo-furan fragment. In the crystal, mol-ecules are linked into supra-molecular layers that stack along [001] by weak C-H⋯O, C-H⋯π and C-S⋯π [3.364 (2) Å] inter-actions.
متن کاملOptimal L(δ1, δ2, 1)-labeling of eight-regular grids
Given a graph G = (V,E), an L(δ1, δ2, δ3)-labeling is a function f assigning to nodes of V colors from a set {0, 1, . . . , kf} such that |f(u) − f(v)| ≥ δi if u and v are at distance i in G. The aim of the L(δ1, δ2, δ3)-labeling problem consists of finding a coloring function f such that the value of kf is minimum. This minimum value is called λδ1,δ2,δ3(G). In this paper we study this problem ...
