Structure of uns-cis-mer (pyridine-2-carboxylato-N,O)(ethylenediaminediacetato-N,N',O,O')cobalt(III)
摘要:
C12H14CoN3O6, M(r) = 355.19, orthorhombic, Pccn, a = 8.838 (3), b = 24.221 (5), c = 12.553 (2) angstrom, V = 2687.03 angstrom 3, Z = 8, D(x) = 1.756 g cm-3, lambda(Mo K-alpha) = 0.7107 angstrom, mu = 12.4 cm-1, F(000) = 1456, room temperature, final R = 0.052 for 2044 unique reflections. The geometry about the Co atom is roughly octahedral with the edda (ethylenediaminediacetato) ligand assuming an uns-cis configuration such that there is one out-of-plane acidate (R) ring and one in-plane amino acidate (G) ring. The pic (picolinato, pyridine-2-carboxylato) ligand bonds to the remaining coordination sites such that the three nitrogen donors are meridional.
