摘要: A series of MII−LnIII azido-containing complexes: [LnNi2(IN)5(N3)2(H2O)3]·2H2O (Ln = NdIII (2), EuIII (3), SmIII (4), LaIII (5)) and [GdCu2(IN)5(N3)2(H2O)3]·2H2O (6) have been prepared hydrothermally by using isonicotinate (IN) azide as bridging ligands with the strategy synergistic coordination. Their structures determined single-crystal X-ray diffraction analyses their magnetic properties probed changing LnIII metal ions 3d ions. All them crystallize in monoclinic space group P2(1)/n. The structural revealed that alternating EE/EO azido−M chain RCOO−/Ln are presented these compounds due to coordination synergy. variable temperature susceptibility studies demonstrate complexes dominated
