Abstract

A new nonanuclear heterometal five-layer sandwich silicotungstate [H₂N(CH₃)₂]₆H₅NaK{[NaMn₈O₆(OAc)₆][A-α-SiW₉O₃₄]₂}·34H₂O (1) has been made under hydrothermal reactions of MnCl₂·4H₂O, KMnO₄, trivacant [A-α-SiW₉O₃₄]^10- {SiW₉} fragment, and [H₂N(CH₃)₂]·Cl in NaOAc-HOAc buffer (pH = 4.8). The polyoxoanion of 1 is a sandwich architecture, in which the nonanuclear heterometal cluster [NaMn₈O₆(OAc)₆]⁷⁺ made of two triangular pyramid clusters [Mn₄O₃(OAc)₃]³⁺ {Mn₄} via a hexacoordinate antitrigonal prism Na⁺ linkage is encapsulated by two trivacant fragments of {SiW₉}. Furthermore, magnetic measurements of compound 1 reveal the existence of antiferromagnetic exchange interactions between the metal centers.
