The title complex, [Cu(H2NCH2CH2NH2)2(CF3COO)2], possesses a crystallographically imposed centre of symmetry. The Cu(II) atom is coordinated by four N atoms [Cu—N 1.985 (2), 2.015 (2) Å] from two chelate ethylenediamine ligands and two O atoms [Cu—O 2.579 (2) Å] from two trifluoroacetate anions in a distorted octahedral geometry. The crystal packing is stabilized by weak intermolecular N—H...O hydrogen bonds.

In the cation of the title complex, [RuCl(NO)(C12H12N2)2](PF6)2, the central RuII ion is sixfold coordinated by a chloride ion and a nitrosyl ligand, which are cis to one another, and by four N atoms of two 4,4′-dimethyl-2,2′-bipyridine ligands, in a slightly distorted octahedral geometry. One of the PF6 − anions is located in a general position, while the other is composed of two half PF6 − anions located on twofold rotation axes. The crystal packing is dominated by C—H...F hydrogen bonds, leading to the formation of a three-dimensional supramolecular structure. There are also C—H...Cl hydrogen bonds present.

Two intramolecular O—H...N hydrogen bonds contribute to the molecular conformation. Weak intermolecular C—H...O hydrogen bonds stabilize the crystal packing.

The structure of the centrosymmetric title complex, [Cu(C5H9O2)2(C6H7NO)2], has the CuIIatom on a centre of inversion. The CuIIatom is six-coordinate with a distorted octahedral geometry, defined by the N and O atoms of the chelating 2-(2-hydroxymethyl)pyridine ligands and two carboxylate O atoms from two monodentate pivalate ions. The crystal packing is stabilized by intermolecular C—H...O and intramolecular O—H...O hydrogen-bond interactions.

The asymmetric unit of the title compound, [Mn(C6H6N4)2(H2O)2](C8H4O4), contains one-half each of the centrosymmetric cation and anion. The MnII atom is coordinated by four N atoms [Mn—N = 2.2168 (14) and 2.2407 (14) Å] from two 2,2′-biimidazole ligands and two water molecules [Mn—O = 2.2521 (14) Å] in a distorted octahedral geometry. Intermolecular N—H...O and O—H...O hydrogen bonds consolidate the crystal packing, which also exhibits π–π interactions between five-membered rings, with a centroid–centroid distance of 3.409 (2) Å.

The asymmetric unit of the title compound, [Re(C12H8N2)(C12H12N2)(CO)3]PF6.·CH3CN, contains one cation, one hexafluoridophosphate anion and one acetonitrile solvent molecule. The ReIion is coordinated by two N atoms from the 1,10-phenanthroline ligand and one N atom from the 1,2-bis(pyridin-4-yl)ethane ligand [mean Re—N = 2.191 (15) Å] and by three carbonyl ligands [mean Re—C = 1.926 (3) Å] in a distorted octahedral geometry. The electrostatic forces and weak C—H...F(O) hydrogen bonds pack cations and anions into the crystal with voids of 82 Å3, which are filled by solvent molecules. The crystal packing exhibits short intermolecular O...O distance of 2.795 (5) Å between two cations related by inversion.

The title compound, [Cu3(C7H3NO4)4(C2H8N2)2]·C2H8N2·4H2O, was obtained by the reaction of copper(II) acetate dihydrate with pyridine-2,6-dicarboxylic acid (H2dipic) and ethylenediamine (en) in an aqueous solution. All of the CuII atoms in the trinuclear centrosymmetric title complex are six-coordinated in a distorted octahedral geometry with N2O4 and N4O2 environments for the outer and central CuII atoms, respectively. Various interactions, including numerous O—H...O and C—H...O hydrogen bonds and C—O...π stacking of the pyridine and carboxylate groups [O...centroid distances = 3.669 (2) and 3.668 (2) Å] are observed in the crystal structure.

The synthesis and crystal structure determination (at 293 K) of the title complex, Cs[Fe(C8H6BrN3OS)2], are reported. The compound is composed of two dianionicO,N,S-tridentate 5-bromosalicylaldehyde thiosemicarbazonate(2−) ligands coordinated to an FeIIIcation, displaying a distorted octahedral geometry. The ligands are orientated in two perpendicular planes, with the O- and S-donor atoms incispositions and the N-donor atoms intranspositions. The complex displays intermolecular N—H...O and N—H...Br hydrogen bonds, creatingR44(18) rings, which link the FeIIIunits in theaandbdirections. The FeIIIcation is in the low-spin state at 293 K.

In the cation of the title complex, [Ru(C31H32N3P2)(C10H8N2)2](PF6)(Br)2·2CH2Cl2·H2O, the ruthenium ion is coordinated in a distorted octahedral geometry by two 2,2′-bipyridine (bpy) ligands and a chelating cationicN-diphenylphosphino-1,3,4,6,7,8-hexahydro-2-pyrimido[1,2-a]pyrimidine [(PPh2)2-hpp] ligand. The tricationic charge of the complex is balanced by two bromide and one hexafluoridophosphate counter-anions. The compound crystallized with two molecules of dichloromethane (one of which is equally disordered about a Cl atom) and a water molecule. In the crystal, one of the Br anions bridges two water moleculesviaO—H...Br hydrogen bonds, forming a centrosymmetric diamond-shapedR42(8) motif. The cation and anions and the solvent molecules are linkedviaC—H...F, C—H...Br, C—H...Cl and C—H...O hydrogen bonds, forming a three-dimensional network.
