The crystal structure of the title salt, [Cu(ClO4)(C8H20N4)]ClO4, is reported. The CuIIion exhibits a square-pyramidal geometry and is coordinated by the four N atoms of the neutral 1,4,7,10-tetraazacyclododecane (cyclen) ligand and an O atom from one perchlorate anion, with the second perchlorate ion hydrogen-bonded to one of the amine N atoms of the cyclen ligand. Additional N—H...O hydrogen bonds between the amine H atoms and the coordinating and non-coordinating perchlorate groups create a three-dimensional network structure. Crystals were grown from a concentrated methanol solution at ambient temperature, resulting in no co-crystallization of solvent.

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.

The asymmetric unit of the organic–inorganic title salt, (C10H28N4)[Cr2O7]2, comprises one half of an 1,4-bis(3-ammoniopropyl)piperazinediium cation (the other half being generated by the application of inversion symmetry) and a dichromate anion. The piperazine ring of the cation adopts a chair conformation, and the two CrO4tetrahedra of the anion are in an almost eclipsed conformation. In the crystal, the cations and anions form a layered arrangement parallel to (001). N—H...O hydrogen bonds between the cations and anions and additional C—H...O interactions lead to the formation of a three-dimensional network structure.

Reaction ofm-aminobenzoic acid (MABA), diethanolamine (DEA) and MnCl2·4H2O led to the formation of the title salt, [Mn(C4H11NO2)2](C7H6NO2)2. In the complex cation, the Mn2+ion is located on an inversion centre and is coordinated by two symmetry-related tridentate DEA molecules, leading to the formation of a slightly distorted MnN2O4octahedron. The MABA−counter-anions are connected to the complex ion by a pair of rather strong O—H...O hydrogen bonds, yielding a 1:2 supramolecular aggregate. Much weaker N—H...O hydrogen bonds connect neighbouring aggregates into a three-dimensional network structure.

Tranexamic acid [systematic name:trans-4-(aminomethyl)cyclohexane-1-carboxylic acid], is an antifibrinolytic amino acid that exists as a zwitterion [trans-4-(ammoniomethyl)cyclohexane-1-carboxylate] in the solid state. Its reaction with copper chloride leads to the formation of a compound with a copper(II) paddle-wheel structure that crystallizes as a hexahydrate, [Cu2Cl2(C8H15NO2)4]2+·2Cl−·6H2O. The asymmetric unit is composed of a copper(II) cation, two zwitterionic tranexamic acid units, a coordinating Cl−anion and a free Cl−anion, together with three water molecules of crystallization. The whole structure is generated by inversion symmetry, with the Cu...Cu axle of the paddle-wheel dication being located about a center of symmetry. The cyclohexane rings of the zwitterionic tranexamic acid units have chair conformations. The carboxylate groups that bridge the two copper(II) cations are inclined to one another by 88.4 (8)°. The copper(II) cation is ligated by four carboxylate O atoms in the equatorial plane and by a Cl−ion in the axial position. Hence, it has a fivefold O4Cl coordination sphere with a perfect square-pyramidal geometry and aτ5index of zero. In the crystal, the paddle-wheel dications are linked by a series of N—H...Cl hydrogen bonds, involving the coordinating and free Cl−ions, forming a three-dimensional network. This network is strengthened by a series of N—H...Owater, Owater—H...Cl and Owater—H...O hydrogen bonds.
