Construction and catalytic effects of solvent- and metal(ii)-dependent products: the process of transformation of 0D structures into 3D structures

Abstract

Self-assembly of Zn(NO3)2 with tris(2-(isoquinolin-5-yloxy)ethyl)amine (L) as a C3-symmetric tridentate N-donor in a mixture of dioxane and acetonitrile gives rise to [NO3@Zn3(NO3)5L2]·2CH3CN in the form of crystals of sandwich-shaped cages encapsulating a nitrate, whereas the same self-assembly reaction in a different mixture, benzene and ethanol, produces [Zn(NO3)L(H2O)]NO3·H2O in the form of crystals of 3D networks with cml {4,62}2{42,610,83} topology. The most interesting feature is the transformation of [NO3@Zn3(NO3)5L2]·2CH3CN crystals into [Zn(NO3)L(H2O)]NO3·H2O crystals in ethanol. A significant difference in heterogeneous transesterification catalysis between the two species is observed. On the other hand, self-assembly of Co(NO3)2 with L gives rise to 3D networks, [Co(NO3)L(H2O)]NO3·H2O, whereas self-assembly of Ni(NO3)2 and Cu(NO3)2 with L produces sandwich-type cages, [NO3@Ni3(NO3)3L2(H2O)6]2NO3·C2H5OH·C6H6 and [NO3@Cu3(NO3)5L2(C2H5OH)]·C2H5OH·2C6H6, respectively, with the latter notably showing heterogeneous catechol oxidation catalytic effects.
