In the title compound, [Cu2(OH)2{C12H7N2(PO3C2H5)}2(H2O)2]·7H2O, two Cu2+cations are bridged by two hydroxide groups, forming a centrosymmetric binuclear complex. Each Cu2+cation is further coordinated by the N atoms of a bidentate ethyl (1,10-phenanthrolin-3-yl)phosphonate anion and a water molecule in a square-pyramidal geometry. In the crystal, a network of O—H...O hydrogen bonds involving the P(O)(O−)(OEt) groups, bridging hydroxyl groups, coordinated and uncoordinated water molecules generates a three-dimensional supramolecular structure. The ethyl group exhibits disorder and was modelled over three sites with occupancies of 0.455, 0.384 and 0.161.

In the title compound, [Mn(C44H28N4)Cl]·2C5H6N2, the MnIIIcentre is coordinated by four pyrrole N atoms [averaged Mn—N = 2.012 (4) Å] of the tetraphenylporphyrin molecule and one chloride axial ligand [Mn—Cl = 2.4315 (7) Å] in a square-pyramidal geometry. The porphyrin macrocycle exhibits a non-planar conformation with majorrufflingandsaddlingdistortions. In the crystal, two independent solvent molecules form dimers through N—H...N hydrogen bonding. In these dimers, one amino N atom has a short Mn...N contact of 2.642 (1) Å thus completing the Mn environment in the form of a distorted octahedron, and another amino atom generates weak N—H...Cl hydrogen bonds, which link further all molecules into chains along theaaxis.

Square Pyramidal Geometry

The title compound, [CuBr(C6H7NO)2]Br·H2O, is an ionic mononuclear complex in which the [CuBr(C6H7NO)2]+cation possesses distorted square-pyramidal geometry. The CuIIcentre is coordinated by two neutral 2-(pyridin-2-yl)methanol (2-pyMeOH) ligands and a terminal bromide ligand. The 2-pyMeOH ligands are coordinated in a bidentate chelating manner through the pyridine N and hydroxy O atoms, forming a five-membered chelate ring with the CuIIcentre. The planes of the pyridine rings are twisted by 58.71 (14)° with respect to each other. The charge is balanced by a noncoordinating bromide anion which, together with a solvent water molecule, links the components through hydrogen bonds into infinite chains propagating along theaaxis. The mononuclear cations appear to associate in pairs through weak interactions between the metal atom of one cation and the halogen atom of an adjacent cation.
