چکیده
In the title compound, [Cu(C(13)H(8)N(4)O(3))(H(2)O)]·3H(2)O, the complex molecule, except for the aqua ligand, is essentially planar [r.m.s. deviation = 0.034 (2) Å]. The coordination polyhedron of the Cu(2+) cation is a square-pyramid, with the aqua ligand at the apex. The compound exhibits a three-dimensional structure, which is is stabilized by O-H⋯O and O--H⋯N hydrogen bonds and π-π inter-actions [centroid-centroid distance = 2.987 (3) Å].

In the title compound, [Cu(C8H5N5O3)(C12H8N2)(H2O)]·3H2O, the Cu(II) cation is O,N,O'-chelated by the 2-amino-7-methyl-4-oxidopteridine-6-carboxyl-ate anion and N,N'-chelated by the 1,10-phenanthroline (phen) ligand. A water mol-ecule further coordinates to the Cu(II) cation to complete the elongated distorted octa-hedral coordination geometry. In the mol-ecule, the pteridine ring system is ess...

In the title coordination polymer, [HgCl(2)(C(11)H(9)N(3))](n), the Hg(II) ion is coordinated by three N atoms from two N-[(E)-pyridin-2-yl-methyl-idene]pyridin-3-amine (L) ligands and two chloride anions in a distorted trigonal-bipyramidal geometry. The two pyridine rings in L form a dihedral angle of 50.0 (2)°. L ligands bridge adjacent HgCl(2) units into polymeric chains propagating in [010]...
