title: 1,2-Di-4-pyridylethane N,N'-dioxide-acetic acid (1/2).
abstract: The title compound, C(12)H(12)N(2)O(2)·2C(2)H(4)O(2), was prepared from 1,2-di-4-pyridylethane, acetic acid, and hydrogen peroxide. The 1,2-di-4-pyridylethane N,N'-dioxide mol-ecule is located on an inversion center. π-π stacking inter-actions between neighboring 1,2-di-4-pyridylethane N,N'-dioxide mol-ecules are observed with a centroid-centroid distance of 3.613 Å, an inter-planar distance of 3.317 Å, and a slippage of 1.433 Å. O-H⋯O hydrogen-bonding inter-actions between 1,2-di-4-pyridylethane N,N'-dioxide and acetic acid mol-ecules result in distinct hydrogen-bonded units made of one N-oxide and two acetic acid mol-ecules. These units are then linked into a three-dimensional network through weaker C-H⋯O hydrogen-bonding inter-actions.
