Bis[N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidato]iron(III) perchlorate monohydrate.

ABSTRACT: The structure of the title salt complex, [Fe(C(12)H(8)N(3)O(2))(2)]ClO(4)·H(2)O, contains one Fe(III) cation, two N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidate (bpca(-)) anions, one perchlorate anion and one water mol-ecule. The Fe(III) cation has an approximate octa-hedral geometry, defined by six N atoms from two bpca(-) anions. The nearly parallel [dihedral angle = 1.50?(1)°] bpca(-) anions form two-dimensional supermolecules along the a axis by the way of weak ?-? stacking inteactirons [centroid-centroid distances = 3.948?(2), 4.000?(2), 3.948?(2), 3.911?(2), 3.897?(2), 3.984?(2) and 3.929?(2)?Å]. Intra- and inter-molecular C-H?O hydrogen bonding occurs. The water mol-ecule [occupancies 0.520?(5) and 0.480?(5)], two carbonyl O atoms [occupancies 0.622?(7) and 0.378?(7)] and the four perchlorate O atoms [occupancies 0.887?(4) and 0.113?(4)] are each disordered over two positions.
