Thiocyanato Coordination Polymers with Isomeric Coordination Networks – Synthesis, Structures, and Magnetic Properties

Julia Werner, Tomče Runčevski, Robert Dinnebier, Stefan G. Ebbinghaus, more

European Journal of Inorganic Chemistry > 2015 > 20 > 3236 - 3245

The reactions of M(NCS)₂ (M = Mn, Fe, and Ni) with 4‐acetylpyridine (4‐Acpy) in water lead to the formation of discrete complexes of composition M(NCS)₂(4‐Acpy)₂(H₂O)₂, in which the metal cations are coordinated only N‐terminally to the thiocyanato anions. When heated, these precursors dehydrate, and some of them transform into compounds of composition [M(NCS)₂(4‐Acpy)₂]_n, in which the metal cations...

Georg Meyer‐Eppler, Filip Topić, Gregor Schnakenburg, Kari Rissanen, more

European Journal of Inorganic Chemistry > 2014 > 15 > 2495 - 2501

Two bis(3‐pyridyl) ligands 1 and 2 based on a planar chiral [2.2]paracyclophane scaffold were synthesized in enantiomerically pure forms. These ligands act as trans‐chelating ligands for square‐planar‐coordinated metal centres such as palladium(II) ions. Upon forming mononuclear homochiral [ML₂] complexes, they show complete chiral self‐sorting in a narcissistic self‐recognition manner as proven by...

Matthias Hülsmann, Andreas Mix, Beate Neumann, Hans‐Georg Stammler, more

European Journal of Inorganic Chemistry > 2014 > 1 > 46 - 50

The cyclic triaminal 1,3,5‐tri‐tert‐butyl‐1,3,5‐triazacyclohexane (TtBuTAC) was treated with tBuLi, but instead of the expected deprotonation at a CH₂ unit, the [(TtBuTAC)(tBuLi)] (2) adduct was formed. This is a monomeric tetracoordinate form of tBuLi; its molecular structure was determined by single‐crystal X‐ray diffraction (XRD) and it is likely to be monomeric in C₆D₆ solution according to ¹H...

Carsten Glock, Claas Loh, Helmar Görls, Sven Krieck, more

European Journal of Inorganic Chemistry > 2013 > 18 > 3261 - 3269

An attempt to prepare Tmp‐C(NDipp)₂Li by treatment of lithium tetramethylpiperidide (Li‐Tmp) with N,N′‐bis(2,6‐diisopropylphenyl)carbodiimide (Dipp‐N=C=N‐Dipp) failed, and ether degradation occurred instead, allowing the isolation of a few crystals of O=CH–CH=C(NH‐Dipp)₂ (1) after hydrolytic work‐up. We then investigated calcium and strontium compounds. Metalation of PrisoH [Priso = iPr₂N–C(N‐Dipp)...

Metalloligands L1 and L2 consisting of directional bis(terpyridine)ruthenium(II) units and bipyridine moieties were constructed by amide formation. From these metalloligands two Ru–Pt heterobimetallic complexes 1 and 2 were derived by a building‐block method by means of platination with [PtCl₂(dmso)₂]. Both bimetallic complexes 1 and 2 feature metal‐to‐ligand charge transfer (MLCT) absorptions, and...
