Nucleation and Crystal Growth of a {V14Sb8O42} Cluster from a {V15Sb6O42} Polyoxovanadate: In‐Situ X‐ray Diffraction Studies
The hydrothermal transformation of the heteroatom polyoxovanadate compound {Ni(ethylenediamine)3}3[V15Sb6O42(H2O)] · 15H2O in water into [{Ni(en)2}2V14Sb8O42] · 5.5H2O was investigated with in-situExpand
Configurational Isomerism in Polyoxovanadates.
A reaction unique to E=Sb results in the formation of the metastable α1 * configurational isomer of the {V14 Sb8 O42 } cluster type, which comprises an inward-oriented vanadyl group and is ca. Expand
Soluble Hetero-Polyoxovanadates and Their Solution Chemistry Analyzed by Electrospray Ionization Mass Spectrometry.
Electrospray ionization mass spectrometry (ESI-MS) is presented as an analytical technique suitable to investigate the structure of complex POM assemblies in solution and to probe the underlying reactivity and formation mechanisms. Expand
New Water-Soluble Cluster Compound {Zn(en)3 }3 [V15 Sb6 O42 (H2 O)]⋅ (Ethylenediamine)3 ⋅10 H2 O as a Synthon for the Generation of Two New Antimonato Polyoxovanadates.
A new antimonato polyoxovanadate synthesized under hydrothermal conditions exhibits remarkable solubility in water and electrospray ionization mass spectrometry investigations on an aqueous solution demonstrate that the cluster core remains fully intact for 72 h. Expand
New insights into the crystallization of polymorphic materials: from real-time serial crystallography to luminescence analysis
Detailed analysis of reaction mechanisms by in situ techniques are important for detecting metastable intermediates, analysing polymorphic transitions and thereby for the discovery of new compounds.Expand
Bond Formation upon Water Removal in an Unusual “Pseudo”-TopotacticReaction Investigated by Single-Crystal Structure and in Situ SynchrotronX‑ray Powder Diffraction Analysis
The new compound [Cu(cyclam)(H2O)]{[Cu(cyclam)]2[HTiNb9O28]}·26H2O (1) (cyclam = 1,4,8,11-tetraazacyclotetradecane) was obtained under solvothermal conditions. Its crystal structure contains a mono...
New pronounced progress in the synthesis of group 5 polyoxometalates
The chemistry of polyoxomolybdates and polyoxotungstates has been systematically developed since their first discovery more than 100 years ago. In contrast, significant progress in the relatedExpand
