چکیده
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 π-π 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.

In the title compound, [Fe(C(12)H(8)N(3)O(2))(2)][Fe(C(12)H(8)N(3)O(2))(CN)(3)]·H(2)O, the Fe(3+) ions in the cation and anion each lie in a slightly distorted octa-hedral coordination environment. The solvent water mol-ecule is disordered over three positions with occupancies of 0.401 (7), 0.322 (7) and 0.277 (6). The water content was confirmed by thermogravimetric data.

The Mn(III) ion in the title complex, [Mn(C(15)H(10)N(3)O)(2)]ClO(4)·H(2)O, is coordinated meridionally by six N atoms from two tridentate N-(8-quinol-yl)pyridine-2-carboxamidate ligands, yielding a distorted octa-hedral coordination geometry. The two ligands are nearly planar and their mean planes are almost perpendicular, with a dihedral angle of 86.7 (2)°.
