Abstract

An indexed powder diffraction pattern and related crystallographic data are reported for cefotaxime sodium salt: 5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid, 3-[(acetyloxy)methyl]-7-[[(2amino-4-thiazolyl)(methoxyimino)-acetyl]amino]-8-oxo, monosodium salt, [6R−[6α,7β(Z)]], C16H16N5NaO7S2. The unit cell dimensions were determined from diffractometer methods, using monochromatic CuKα1 radiation, and evaluated by indexing programs. The monoclinic cell found for cefotaxime sodium was a=13.063(2) Å, b=8.916(2) Å, c=9.726(2) Å, β=107.34(2)°, Z=2, space groups: P21 (No. 4) or P21/m (No. 11), Dx=1.467 g/cm3.
