We consider timed automata whose clocks are imperfect. For a given perturbation error 0 < ε < 1, the perturbed language of a timed automaton is obtained by letting its clocks change at a rate within the interval [1 ε, 1 + ε]. We show that the perturbed language of a timed automaton with a single clock can be captured by a deterministic timed automaton. This leads to a decision procedure for the...
In the heterometallic title bulky amido complex, [LiNa(C15H21N2Si)2(C6H16N2)], both alkali metal ions are four-coordinated with distorted tetra-hedral geometries. The Li(+) ion is N,N'-chelated by the N-silylated amido ligand, with Li-N = 2.015 (5) and 2.074 (5) Å. The two amido ligands are arranged cis to each other. The mol-ecule exhibits a twofold rotational symmetry operation along the Li-N...

Bis{4-[(Z)-N′-(4-hydroxybenzylidene)hydrazino]-8-(trifluoromethyl)quinolinium} sulfate dihydrate
The title compound, 2C(17)H(13)F(3)N(3)O(+)·SO(4) (2-)·2H(2)O, crystallizes with four independent cations (A, B, C and D) in the asymmetric unit, which is composed of two groups of two cations, one anion and two water mol-ecules (Z' = 2). The dihedral angle between the mean planes of the 4-hydroxy-phenyl and quinolinium groups is 8.9 (7)° in A, 30.1 (6)° in B, 28.8 (8)° in C and 12.8 (1)° in D....
The title compound, C(17)H(21)N(3)O(3), has a Z configuration about the N=N double bond. The molecular conformation is stabilized by intramolecular N-H⋯O and O-H⋯N hydrogen bonds.
