crystal data
(±)Co(en)3F3, [Co(C2H8N2)3]F3, C6H24CoN63 +. 3F−, crystallizes in three different forms, F, A and P. F and A forms are orthorhombic with space groups Fmmm and Amam respectively (or the non-centrosymmetric equivalent groups F2mm and Ama2 types). Their lattice constants are (F) a = 13.448 (3), b = 28.855 (8) and c = 9.462 (4) Å; (A) a = 12.262 (2), b = 28.863 (9) and c = 9.386 (2) Å. The P form is monoclinic with space group P21/n and unit cell a = 12.575 (5), b = 27.65 (1) and c = 19.65 (1) Å, β = 90.5°. X-ray powder diffraction data are quoted for F and A forms.
