TLDR
The cryptand L can accommodate a Co(II) ion inside the cavity at the tren end, forming a CoN4 complex as mentioned in this paper, which is a distorted trigonal bipyramidal complex.Abstract:
The cryptand L can accommodate a Co(II) ion inside the cavity at the tren end, forming a CoN4 complex. The Co(II) ion further accepts a SCN- anion, forming a distorted trigonal bipyramidal complex....read more

A Cobalt(II)‐containing Metal‐Organic Framework Showing Catalytic Activity in Oxidation Reactions
TL;DR: In this article, a metal-organic framework (MOF) containing redox active CoII atoms, [CoII(BPB)]·3DMF (1), has been prepared from the solvothermal reaction of CoII nitrate and 1,4-bis(4′-pyrazolyl)benzene (H2-BPB) in dimethylformamide (DMF).

Heteroditopic cryptands of tunable cavity size: imposition of distorted geometry onto Copper(II) and Nickel(II) and molecular recognition of water molecules
TL;DR: In this paper, the complex behavior of a previously described heteroditopic cryptand and a newly synthesized cryptand L2 toward transition metal ions has been described and the UV−vis spectral and magnetic studies of the complexes are consistent with the mononuclear nature of the cryptates.

Enhanced Catalysis Activity in a Coordinatively Unsaturated Cobalt-MOF Generated via Single-Crystal-to-Single-Crystal Dehydration
TL;DR: It is interestingly found that heterogeneous catalytic oxidation of cyclohexene in 1a not only gives the higher conversion of 73.6% but also shows very high selectivity toward 2-cyclohexenes-1-one (ca. 64.9%), as evidenced in high turnover numbers based on the open Co(II) sites of 1a catalyst.

Laterally non-symmetric aza-cryptands: synthesis, catalysis and derivatization to new receptors
TL;DR: Laterally non-symmetric cryptands are defined as cryptands where the two bridgehead atoms like N or C or benzene units are connected by three bridges such that the donor atoms about the bridgeheads are different as mentioned in this paper.

TL;DR: In this paper, it was shown that manganese complexes derived from l,4,7-trimethyl-l, 4,4-7-triazacyclononane and related ligand systems act as highly effective catalysts for the bleaching of stains by hydrogen peroxide at low temperatures.

Spectral-structural correlations in high-spin cobalt(II) complexes
TL;DR: In this paper, the spectral and magnetic properties of simple high spin cobalt(II) complexes are reviewed with the aim of showing how it is possible to relate the experimental data to the electronic structure and the coordination geometry of the complexes.

Metal Complex-Catalyzed Epoxidation of Olefins by Dioxygen with Co-Oxidation of Aldehydes. A Mechanistic Study
TL;DR: It is concluded that the principal role of the metal complexes is to aid in the initiation step for the free radical autoxidation of the aldehyde and that acylperoxy radicals generated in the Autoxidation reaction (or metal complexes formed by complexation of the acyl peroxy radicals) are the active epoxidizing agents.
