Crystal structure of 4-chloro-2-[(5-ethoxy-1,3,4-thiadiazol-2-yl)methyl]-5-(piperidin-1-yl)pyridazin-3(2H)-one

Crystal structure of 4-chloro-2-[(5-ethoxy-1,3,4-thiadiazol-2-yl)methyl]-5-(piperidin-1-yl)pyridazin-3(2H)-one

In the title molecule, C14H18ClN5O2S, the six atoms of the 1,6-dihydropyridazine ring are essentially coplanar (r.m.s. deviation = 0.008 Å), and the dihedral angle between this and the 1,3,4-thiadiazole ring is 62.06 (10)°. In the crystal, centrosymmetrically related molecules are linked by intermol...

Description
Summary:In the title molecule, C14H18ClN5O2S, the six atoms of the 1,6-dihydropyridazine ring are essentially coplanar (r.m.s. deviation = 0.008 Å), and the dihedral angle between this and the 1,3,4-thiadiazole ring is 62.06 (10)°. In the crystal, centrosymmetrically related molecules are linked by intermolecular C—H—O hydrogen bonding to form a supramolecular dimer. The terminal ethyl group is statistically disordered over two positions.
