title: Structure of the pseudomonad fungal antibiotic phenazine-1-carboxylic acid.
abstract: C13H8N2O2, Mr = 224.2, monoclinic, Cc, a = 3.955 (1), b = 19.278 (4), c = 13.468 (1) A, beta = 98.90 (2) degrees, V = 1015 (2) A3, Z = 4, D chi = 1.468 Mg m-3, lambda (Mo K alpha) = 0.7107 A, mu = 0.061 mm-1, F(000) = 464, T = 293 (2) K, R = 0.047 for 571 observed reflections. The crystal-structure determination of the title compound, a phenazine antibiotic from Pseudomonas fluorescens 2-79 (NRRL B-15132), confirms its structure as phenazine-1-carboxylic acid. The molecular packing is described by discrete stacks of molecules parallel to the a axis with the distance between the essentially planar molecules being ca 3.96 A; there are no significant intermolecular contacts in the lattice.
