Recognition of giant cluster anions by a protonated porphyrin trimer: detection by fast-atom bombardment (FAB) mass spectrometry
Abstract
Anions such as PW12O403–, SiW12O404– and OS10C(CO)242– are recognised and bound by a porphyrin cyclic trimer of complementary size and charge; these second-sphere coordinate cluster complexes were detected by FAB mass spectrometry.
