In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1111-67-7, name is Cuprous thiocyanate, introducing its new discovery. Quality Control of Cuprous thiocyanate
A novel two-dimensional CuSCN network templated by 2,2?-dimethyl-1, 1?-(butane-1,4-diyl)bis(1H-imidazol-3-ium) cations
The cation-templated self-assembly of 1,4-bis(2-methyl-1Himidazol-1-yl) butane (bmimb) with CuSCN gives rise to a novel two-dimensional network, namely catena-poly[2,2?-dimethyl-1,1?-(butane-1,4-diyl)bis(1H-imidazol-3- ium) [tetra-mu2-thiocyanato-kappa4S: S;kappa4S:N-dicopper(I)]], {(C12H20N 4)[Cu2-(NCS)4]}n. The CuI cation is four-coordinated by one N and three S atoms, giving a tetrahedral geometry. One of the two crystallographically independent SCN- anions acts as a mu2-S:S bridge, binding a pair of CuI cations into a centrosymmetric [Cu2(NCS)2] subunit, which is further extended into a twodimensional 44-sql net by another kind of SCN – anion with an end-to-end mu2-S:N coordination mode. Interestingly, each H2bmimb dication, lying on an inversion centre, threads through one of the windows of the two-dimensional 44-sql net, giving a pseudorotaxane-like structure. The two-dimensional 44-sql networks are packed into the resultant three-dimensional supramolecular framework through bmimb-SCN N-H…N hydrogen bonds.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of Cuprous thiocyanate, you can also check out more blogs aboutQuality Control of Cuprous thiocyanate
