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.
