Accepted 16 October 2017

A new polymorph of 2,6-di­amino­pyridine

Sublimation yielded a new polymorph of 2,6-di­amino­pyridine, a common ingredient in and a synthetic precursor to many colorants.

Accepted 16 October 2017

Deciphering composition and connectivity of a natural product with the assistance of MS and 2D NMR

The structure of a three-component cocrystal of natural products contained extensive positional disorder in one of the mol­ecules. The identity of the disordered mol­ecule was established by 2D NMR and MS thereby making disorder modelling and structural refinement possible.

Accepted 13 October 2017

Preparation and characterization of two new CuII supra­molecular coordination polymers incorporating sulfobenzoate and flexible heterocyclic ligands

Two new CuII supra­molecular coordination polymers based on the multifunctional ligand 2-amino-4-sulfo­benzoic acid (H2asba) have been synthesized and characterized.

Copper(II) bis­(4,4,4-tri­fluoro-1-phenyl­butane-1,3-dionate) complexes with pyridin-2-one, 3-hy­droxy­pyridine and 3-hy­droxy­pyridin-2-one ligands: mol­ecular structures and hydrogen-bonded networks

The influence of tautomeric forms and different coordination modes has been studied with respect to the formation of hydrogen-bonded networks in (4,4,4-tri­fluoro-1-phenyl­butane-1,3-dionato)copper(II) moieties in the presence of pyridin-2-one, 3-hy­droxy­pyridine and 3-hy­droxy­pyridin-2-one.

A novel tetra­zolate- and cyanide-bridged three-dimensional heterometallic coordination polymer: crystal structure, thermal stability and magnetic properties

A tetra­zolate- and cyanide-bridged CuII–CoIII bimetallic coordination polymer is the first example of a trinodal (6,8,8)-connected three-dimensional network and is constructed from anionic [Co(CN)6]3− and cationic [(Cu1)2(tta)2]2+ and [(Cu2Cu3)(tta)3]+ units. A magnetic investigation shows anti­ferromagnetic inter­actions between the paramagnetic CuII ions.

Accepted 3 October 2017

Asymmetric structure of cis-{N-[(anthracen-9-yl)meth­yl]ethane-1,2-di­amine-κ2N,N′}­bis­(pyridine-κN)platinum(II) dinitrate

In many cases, complexes of platinum and other metals have a symmetrical structure. In contrast, in the platinum(II) complex with pyridine and N-[(anthracen-9-yl)meth­yl]ethane-1,2-di­amine as ligands, the molecular structure is asymmetric. Only one of the two pyridine rings is π-stacked with the anthracene ligand enhancing the asymmetry.
