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...
متن کاملCrystal structure of 4,6-dichloro-5-methylpyrimidine
The title compound, C5H4Cl2N2, is essentially planar with an r.m.s. deviation for all non-H atoms of 0.009 Å. The largest deviation from the mean plane is 0.016 (4) Å for an N atom. In the crystal, mol-ecules are linked by pairs of C-H⋯N hydrogen bonds, forming inversion dimers, enclosing an R (2) 2(6) ring motif.
متن کاملCrystal structure of 5-hydroxymethyl-2-methoxyphenol
In the title compound, C8H10O3, the hy-droxy-methyl group is twisted by 74.51 (13)° from the plane of the benzene ring to which it is connected. By contrast, the benzene and meth-oxy groups are almost coplanar, making a dihedral angle of 4.0 (2)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
متن کاملCrystal structure of 5-hydroxy-5-propylbarbituric acid
Mol-ecules of the title compound, C7H10N2O4, systematic name 5-hy-droxy-5-propyl-pyrimidine-2,4,6(1H,3H,5H)-trione, form a hydrogen-bonded framework which is based on three independent hydrogen bonds, N-H⋯O(carbon-yl), N-H⋯O(hy-droxy) and O-H⋯O(carbon-yl). This framework has the topology of the 5-connected nov net. Each mol-ecule is linked to five other mol-ecules via six hydrogen bonds, and th...
متن کاملSYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]
The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
