Two coordination polymers of [CuSCN(INH)] n (1) and [CuCl(INH)] n (2) have been synthesized (where INH = isoniazid). Their crystal structures have been determined by X-ray single crystal diffraction and both of them belong to monoclinic system. The Cu(I) ions in 1 and 2 all adopt distorted tetrahedral geometries. The complex 1 belongs to Cc space group and the cell parameters are: a = 44.370(2) A, b = 3.811(3) A, c = 30.2800(19) A, beta = 132.87(3) and Z = 4. The Cu(I) ion in 1 is coordinated to three SCN groups and one INH ligand and such coordination model result in a 2D networks construction. Complex 2 crystallizes in the P21/c space group and the cell parameters are: a = 7.0319(13) A, b = 18.367(3) A, c = 6.0644(11) A, beta = 93.466(2) and Z = 4. Each copper atom in 2 is ligated by two INH ligands and two chlorine groups. Two copper atoms are asymmetrically bridged by two chlorine ligands to form a Cu2Cl 2 unit. Each Cu2Cl2 fragment is bridged by four INH groups to form a 2D layer structure.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Reference of 1111-67-7, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about Reference of 1111-67-7
