摘      要：New steroid dimer,ethylene bridged bis-carbamate(3) was synthesized from cholic acid in few steps. Complexes of 3 with lanthanum(Ⅲ) and calcium(Ⅱ) nitrates were prepared in reaction of 3 and appropriate metal salts. They were characterized by spectral data(Infrared(IR) ,ultraviolet-visible(UV/Vis) ,nuclear magnetic resonance(NMR) spectroscopy and fast-atom bombardment(FAB) ,electrospray(ESI) and matrix-assisted laser desorption/ionization mass spectrometry(MALDI-MS)) and elemental analysis. The similarity in complexing behavior of steroidal dimer toward calcium and lanthanum ions was observed.
