Pyrazino[2,3-b]indolizine-10-carbonitrile
In the crystal structure of the title compound, C(11)H(6)N(4), neighbouring mol-ecules are linked into inversion dimers through pairs of weak C-H⋯N hydrogen bonds, forming an R(2) (2)(10) ring motif. The dimers forming this motif are further linked by π-π inter-actions. With respective average deviations from planarity of 0.004 (2) and 0.004 (1) Å, the pyrazino[2,3-β]indolizine and cyano fragme...
متن کامل10-Methoxybenzo[g]imidazo[1,2-a][1,8]naphthyridine-4-carbonitrile
In the title compound, C(16)H(10)N(4)O, both the meth-oxy and nitrile substituents lie in the plane defined by the benzo[g]imidazo[1,2-a]-1,8-naphthyridine ring system, resulting in a nearly planar geometry for the entire mol-ecule (r.m.s. deviation of the non-H atoms from the mean plane is 0.044 Å). In the solid-state, the mol-ecules form a three-dimensional polymer through inter-molecular C-H...
متن کاملQuinoxaline-2-carbonitrile
In the title compound, C(9)H(5)N(3), the quinoxaline ring is essentially planar, with a maximum deviation of 0.012 (1) Å. Short inter-molecular distances between the centroids of the 2,3-dihydro-pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter-actions. In the crystal packing, the mol-ecules are linked via two pairs of inter-molecular C-H⋯N inter-actions, forming R(2...
متن کامل1,3-Diiodoazulene-2-carbonitrile
In the title compound, C11H5I2N, the two iodine-atom substitutents with their large atomic sizes lead to short intra-molecular I⋯H distances (3.01 Å). In the crystal, the tris-ubstituted azulene system forms π-stacks [centroid-centroid distance = 3.6343 (11) Å] along the a-axis direction, showing the characteristic azulene inter-action mode between the electron-rich five-membered ring and the e...
متن کاملQuinoline-2-carbonitrile
In the title compound, C(10)H(6)N(2), the mol-ecule is almost planar, with an r.m.s. deviation of 0.014 Å. The dihedral angle between the aromatic rings is 1.28 (16)°. In the crystal, mol-ecules are stacked along the a axis by way of weak aromatic π-π stacking inter-actions between the benzene and pyridine rings of adjacent mol-ecules [centroid-centroid separation = 3.7943 (19) Å].
