Crystal Structure of IN,N'-di(n-propyl)^,4'-bipyridinium] (7,7,8,8-Tetracyano-p-quinodimethanide)J~
The 4:1 complex salt formed between 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) and the N,N'-di(n-propyl)-4,4 ' -bipyridinium dication (DPrBP) is monoclinic, space group P21 /c , with a = 1 3 . 3 3 4 ( l ) , b = 25.954(3), c = 7.877(1) A, 0 = 93.66(1)°. The structure was solved by the Patterson method and refined to R = 0.070 for 3277 unique reflections. The T C N Q moieties stack plane-to-plane...

Little is known about cell death in spinal cord tissue following compression injury, despite compression being a key component of spinal injuries. Currently models are used to mimic compression injury in animals and the effects of the compression evaluated by observing the extent and duration of recovery of normal motor function in the days and weeks following the injury. A fiber-optic photople...

the synthesis of a wide variety of phthalein1,2 and fluoran dyes.3 The structural chemistry of these acids has drawn much interest because of the properties of the ring-chain tautomerism in solution4 and the polymorphism in the crystal state.5 Lalancette et al. reported that the simplest acid, o-benzoylbenzoic acid (BBA) crystallizes in the two polymorphic forms: hydrous and anhydrous.6 In the ...
متن کاملOn the Trinomial Arcs J ( p , k , r , n )
We study the trinomial arcs J(p, k, r, n) and we prove the monotonicity of this category of arcs. Mathematics Subject Classification: 26C10, 30C15, 14H45, 26A48
متن کاملCrystal structure of N,N'-(p-chlorophenyl)thiourea.
mercury poisoning in humans,1 we are currently working on the synthesis of a new series of chelating agents, such as N,N′-(pchlorophenyl)thiourea (Fig. 1). In this paper, we present the crystal structure of (I). It is important to mention that there are a few structure reports exclusively concerning substitutedthiourea derivatives, which may be due to the difficulty in preparing crystals for X-...
