초록

표제화합물의 결정구조는 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium, $C_{16}H_{19}N_2$와 tosylate, $C_7H_7SO_3$의 불연속한 이분자체로 구성되어 있다. 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium 분자는 중간에 있는 C=C double bond에서 trans conformation을 가지고 있으며 phenyl 및 pyridyl ring들간의 이면각은 $5.7(2)^{\circ}$을 이루어 전분자는 $0.138(8){\AA}$ 내에서 평면을 이루고 있다. Tosylate 분자들은 거리가 각각 2.855(9) and $2.899(8){\AA}$인 O-H...O 수소결합으로 연결된 이분자체를 나타내고 있다. 이 두 분자간의 가장 가까운 거리는 O(3)와 C(16) 원자간의 $3.10(1){\AA}$이다.

The crystal structure of the title compound consists of discrete 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium, $C_{16}H_{19}N_2$, and tosylate, $C_7H_7SO_3$, dimer. The 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium molecule has a trans conformation at the central C=C double bond: the dihedral angle between the phenyl and the pyridyl rings is $5.7(2)^{\circ}$ and the whole molecule is planar within $0.138(8){\AA}$. Tosylate molecules display hydrogen-bonded dimers with the O-H...O distances of 2.855(9) and $2.899(8){\AA}$, respectively. The shortest intermolecular contact is the distance $3.10(1){\AA}$ between O(3) and C(16).
