2-Amino-pyridinium 5-(5-chloro-2,4-dinitro-phen-yl)-1,3-dimethyl-2,4-dioxo-1,2,3,4-tetra-hydro-pyrimidin-6-olate


, : 2-Amino-pyridinium 5-(5-chloro-2,4-dinitro-phen-yl)-1,3-dimethyl-2,4-dioxo-1,2,3,4-tetra-hydro-pyrimidin-6-olate. Acta Crystallographica. Section E, Structure Reports Online 67(Pt 12): O3475-O3475

In the title mol-ecular salt, C(5)H(7)N(2) (+)·C(12)H(8)ClN(4)O(7) (-), the dihedral angle between the aromatic rings of the anion is 51.88 (6)°. One of the nitro groups is disordered over two orientations in a 0.710 (6):0.290 (6) ratio. In the crystal, the cations and anions are linked by N-H⋯O hydrogen bonds, generating infinite ribbons extending along [100] which incorporate R(4) (4)(22) ring motifs. Weak C-H⋯O inter-actions also occur.

Predictors of future stroke events gain importance in vascular medicine. Herein, we investigated the value of the ankle-brachial index (ABI), a simple non-invasive marker of atherosclerosis, as stroke predictor in addition to established risk fact...
