The five-coordinate CuIIatom in the title complex [CuCl2(C16H19N3)]·0.5C4H10O, adopts a near-ideal square-pyramidal geometry (τ-5 = 0.01). The apical Cu—Cl distance is 0.2626 (6) Å longer than the basal Cu—Cl distance. Weak C—H...Cl interactions between pyridine rings and the Cl atoms of adjacent complex molecules are present. The solvent molecule, located on a twofold rotation axis, is situated in the voids of this arrangement. Copper atoms coordinated by tridentate nitrogen-containing ligands have been found to be excellent promoters of Atom Transfer Radical Addition (ATRA) reactions.

The title compound, bis(1,2-diphenyl-2-sulfanylideneethanethiolato-κ2 S,S′)(1,3,5-triaza-7-phosphaadamantane-κP)cobalt(II) dichloromethane hemisolvate, [Co(pdt)2(PTA)]·0.5C2H4Cl2 or [Co(C14H10S2)2(C6H12N3P)]·0.5C2H4Cl2, contains two phenyldithiolene (pdt) ligands and a 1,3,5-triaza-7-phosphaadamantane (PTA) ligand bound to cobalt with the solvent 1,2-dichloroethane molecule located on an inversion center. The cobalt core exhibits an approximately square-pyramidal geometry with partially reduced thienyl radical monoanionic ligands. The supramolecular network is consolidated by hydrogen-bonding interactions primarily with nitrogen, sulfur and chlorine atoms, as well as parallel displaced π-stacking of the aryl rings. The UV–vis, IR, and CV data are also consistent with monoanionic dithiolene ligands and an overall CoII oxidation state.

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.

The mononuclear title complex, [Fe(CF3O3S)(C5H7O2)2(C4H8O)] or [Fe(acac)2(OTf)(THF)] (acac = acetylacetonate; OTf = trifluoromethanesulfonate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe3+atom in a slightly distorted octahedral environment [Fe—O bond-length range = 1.9517 (11)–2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622 (16):0.378 (16). Weak intermolecular C—H...O and C—H...F hydrogen-bonding interactions generate a two-dimensional supramolecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis(acetylacetonato)iron(III) complex.

In the mononuclear title complex, [CuBr(C20H12N3O2)(C3H7NO)], synthesized from the quinoline-derived reduced Schiff base 4-(quinolin-2-ylmethyl)aminophenol, the coordination geometry around Cu2+is distorted square-pyramidal, comprising a bromide anion at the apex [Cu—Br = 2.4671 (5) Å]. The base of the pyramid is built up from one dimethylformamide O-atom donor [Cu—O = 2.078 (2) Å] and three N-atom donors from the monoanionic, tridentate bis(quinolin-2-ylcarbonyl)diimide ligand [Cu—Ndiimide= 1.941 (3) Å, and Cu—Nquinolyl= 2.060 (3) and 2.049 (3) Å]. An intramolecular C—H...O occurs. In the crystal, weak methyl and aromatic C—H...Br and formyl C—H...Ocarbonylhydrogen-bonding interactions generate an overall layered structure lying parallel to (001).
