Influence of the alkali cation size on the Cu2+ coordination environments in (AX)[Cu(HSeO3)(2)] (A = Na, K, NH4, Rb, Cs; X = Cl, Br) layered copper hydrogen selenite halides
Using solution evaporation techniques, we succeeded in preparation of new members essentially extending the layered copper hydrogen selenite family, (AX)[Cu(HSeO3)(2)] with A=Na, K, Rb, Cs, and NH4, and X= Cl and Br. Bromides and chlorides are isostructural in the family of described new compounds crystallizing in three different structure types. (NaX)[Cu(HSeO3)(2)] and (KX)[Cu(HSeO3)(2)] (X = CI, Br) are monoclinic, whereas (AX) [Cu(HSeO3)(2)] (A = NH4, Rb, Cs; X = Cl, Br) are orthorhombic. Upon the enlargement of the A’ ionic radii inserted in the interlayer between the neighboring [Cu(HSeO3)(2)] slabs, the effective distance is increasing and results in essential elongation of the apical Cu-X (X = Cl, Br) distances. Three different types of CuO4Xn (n=0-2) polyhedra are formed. The observed trend is an interesting example of the chemical tuning of the Cu2+ coordination environments.
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. you can also check out more blogs about 29823-18-5. Recommanded Product: Ethyl 7-bromoheptanoate.
