摘要：

(Chemical Equation Presented) Control, but not a freak: A series of dodecanuclear coordination clusters of NiII and CoII with isostructural frameworks is prepared with unparalleled structural and compositional control. At different pH values, the respective clusters can be detected in solution by cryospray mass spectrometry. The positions of the metal centers in the mixed-metal clusters are determined from the magnetic properties. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
