Popis:	Trinuclear Ni3S4N3 clusters were obtained from (1S,2S)-1-monothiasulfato-1-phenyl-2-(methylammoniumyl)propane (tpmp). Three homochiral ligand molecules together with three Ni II ions give rise to a cone-shaped cluster topped by a l3-sulfide ion. Each Ni II is in a distorted planar geometry. X-ray structural studies showed that in three cases the three phenyl groups form the rim of a cage which contains R-OSO3 (R ¼ C2H5 ,C 3H7) or nitrate anions. The alkyl sulfates were generated during the synthesis reaction, and are hydrogen-bonded through the oxygen atoms to the amine nitrogen atoms. The corresponding compound with the methyl sulfate anion (MeOSO3) reacts with Fe III nitrate to form a similar compound in which the nitrate anion occupies the cavity and its crystals were analyzed by X-ray diffraction. 2004 Elsevier Ltd.
