The title mononuclear MnII complex, [Mn(C13H14N2)4(H2O)2](PF6)2·H2O, is isostructural with the previously reported ZnII complex. The metal center is coordinated by four monodentate 1,3-di-4-pyridylpropane (L1) ligands and two water molecules. One L1 ligand is affected by disorder of two propane C atoms, which are distributed over two positions, with occupancies 0.771 (8)/0.229 (8). The asymmetric unit is completed by one solvent water molecule and two PF6 − anions, both disordered over two positions, with occupancies for F atoms of 0.621 (10)/0.379 (10) for one anion and 0.69 (2)/0.31 (2) for the other. Uncoordinated N atoms of pyridyl groups belonging to L1 and water molecules are involved in hydrogen bonds, with D...A separations ranging from 1.85 (4) to 2.07 (4) Å and D—H...A angles from 169 (3) to 174 (4)°.

The ZnIIatom in the title polymeric compound, {[Zn(C8H6NO4)2(H2O)2]·2H2O}n, lies on a center of inversion and is coordinated by two amine N atoms and two carboxylate O atoms from two 3-amino-5-carboxybenzoate anions along with two water molecules in a distorted octahedral geometry. The bridging nature of the anion generates a layer motif parallel to (100). Hydrogen bonds of the N—H...O and O—H...O types exist in the structure. One H atom of the coordinated water molecule and one H atom of the solvent water molecule are each disordered over two positions in a 1:1 ratio.

One CuIIcation isN,N′,N",O-chelated by anN-[3-(dimethylamino)propyl]-N′-(2-hydroxyphenyl)oxamide trianion in a distorted square-planar geometry, whereas the other CuIIcation isO,O′-chelated by the oxamide moiety of the anion andN,N′-chelated by a 1,10-phenanthroline-5,6-dione molecule, and a water molecule further coordinates the second CuIIcation, completing a distorted square-pyramidal coordination geometry. In the crystal, classical O—H...O hydrogen bonds, weak C—H...O hydrogen-bonding interactions and π–π stacking interactions link the complex cations, anions and solvent water molecules into a three-dimensional supramolecular architecture. In the crystal, the dimethylaminopropyl unit of the oxamide anion is disordered over two positions with an occupancy ratio of 0.561 (11):0.439 (11); the solvent water molecule is also disordered over two positions, the occupancy ratio being 0.207 (10):0.293 (10).

The Mean

In the title chromone-tethered benzohydrazide derivative, C21H20N2O7·H2O, the atoms of the 4H-chromen-4-one segment are essentially coplanar (r.m.s. deviation = 0.0073 Å) with the largest deviation from the mean plane [0.012 (3) Å] being found for the benzene C atom. The dihedral angles between the chromone segment and the hydrazide plane and between the chromone segment and the benzene ring of the trimethoxybenzene unit are 24.67 (9) and 41.28 (8) Å, respectively. The molecule is connected to the solvent water molecule by O—H...O hydrogen bonds and weak C—H...O interactions. Additional N—H...O interactions are observed and together they link the molecules into chains forming a two-dimensional network along (011).

The structure of the title compound, [Co2(C7H7N2O2)4(H2O)2]·2H2O, consists of a centrosymmetric binuclear [Co2(4-Apha)4(H2O)2] complex molecule (4-AphaH = 4-aminophenylhydroxamic acid), and two solvent water molecules. Each CoII cation is six coordinate, binding five oxygen atoms from three 4-Apha− ligands and a water molecule in a slightly distorted octahedral geometry. Two of the 4-Apha− ligands bridge two neighbouring CoII ions to form the binuclear complex. A three-dimensional network structure is generated by O—H...O, N—H...O, and N—H...N hydrogen bonds.
