In MeCN, ...

Crystal structure of di-[mu]-iodido-bis­[bis(aceto­nitrile-[kappa]N)copper(I)]

Crystal structure of the two-dimensional coordination polymer poly[di-μ-bromido-bis­(μ-tetra­hydro­thiophene)­dicopper(I)]

The polymeric title compound, [Cu2Br2(C4H8S)2]n, CP1, represents an example of a two-dimensional coordination polymer resulting from reaction of CuBr with tetra­hydro­thio­phene (THT) in MeCN solution. The two-dimensional layers consist of two different types of rhomboid-shaped dinuclear ...


Disciplines : chemistry, organic

Disciplines : chemistry, organic
Collected date : from 2018 to 2019

A new pyrrole-substituted terpyridine derivative that possesses an allene moiety was obtained as an “unexpected” sole product during an attempt to alkylate the N-atom of pyrrole with propargyl bromide in order to obtain an alkyne-functionalized terpyridine.


Disciplines : chemistry, organic
Collected date : 2020

A new thiophene-substituted terpyridine derivative has been prepared through the reaction between 5-n-propylthiophene-2-carboxaldehyde and 2-acetylpyridine. This terpyridine derivative bears an alkyl chain linked via a thiophene heterocycle.

The 10 parsec sample
