Crystal and X-ray powder diffraction data for cefotaxime sodium salt, C16H16N5NaO7S2

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 -caboxylic acid, 3-[(acetyloxy)methyl]-7-[[(2-amino-4-thiazolyl)(methoxyimi no)-acetyl] amino]-8-oxo, monosodium salt, [6R-[6 alpha,7 beta(Z)]], C16H16 N5NaO7S2. The unit cell dimensions were determined from diffractometer meth ods, using monochromatic CuK alpha(1) radiation, and evaluated by indexing programs. The monoclinic cell found for cefotaxime sodium was a = 13.063(2) Angstrom(,) b = 8.916(2) Angstrom, c = 9.726(2) Angstrom, beta = 107.34(2) degrees, Z = 2, space groups: P2(1) (No. 4) or P2(1)/m (No. 11), D-x =1.467 g/cm(3).
