A1 - Dittrich, Birger T1 - Redetermination and invariom refinement of 1-cyclopropyl-6-fluoro-4-oxo-7-(piperazin-4-ium-1-yl)-1,4-dihydroquinoline-3-carboxylate hexahydrate at 120 K Y1 - 2008 VL - 64 IS - 12 SP - o2354 EP - o2355 JF - Acta Crystallographica Section E Structure Reports Online DO - 10.1107/S1600536808037409 DO - 10.23689/fidgeo-2459 N2 - The structure of the title compound, C17H18FN3O3 6H2O, has been redetermined at 120 K. An invariom refinement, a structural refinement using aspherical scattering factors from theoretically predicted multipole population parameters, yields accurate geometry and anisotropic displacement parameters, including hydrogen-bonding parameters. All potential hydrogen-bond donors and acceptors are involved in hydrogen bonding, forming an intricate three-dimensional network of N—H O and O—H O bonds UR - http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/6772 ER -
