Abstract
일련의 산소 및 황 가교결합의 이핵 몰리브덴(V) 착물, Mo2O4L2, Mo2O3L4, Mo2O2S2L2, 그리고 Mo2O2S3L2, L = bis(hydroxyethyl)dithiocarbamate을 합성하였다. 말단과 가교의 산소결합 착물은 수용액에서 (PyH)2MoOCl5 혹은 MoCl5와 리간드의 반응으로부터 합성되었고, Mo2O42+핵에서 산소가 황으로 치환된 착물, Mo2O2S2L2, and Mo2O2S3L2의 클로로포름 용액에 트리페닐포스핀을 가하므로 합성되었다. 한편, Mo2O2S2L2착물은 sodium dithionite 존재하에서 (NH4)2MoS4와 리간드의 수용액으로부터 얻어졌다. 합성한 착물에 대한 원소분석과 IR, UV-vis, nmr, 그리고 mass 스펙트라에 의한 착물의 분광학적 성질을 조사하였다. 또한 디메틸술폭시드 용액에서 이들 착물의 전기화학적 성질을 순환전압-전류법으로 조사하였다.

A series of oxo-and sulfido-bridged molybdenum (V) complexes, Mo2O4L2, Mo2O3L4, Mo2O2S2L2, and Mo2O2S3L2 [L = bis(hydroxyethyl)dithiocarbamate] have been prepared. The complexes with bridging and terminal oxo groups have been synthesized by the reactions of (PyH)2MoOCl5 or MoCl5 and ligand in water. One of the rest two complexes, in which bridging and terminal oxo groups have been replaced by sulfido in Mo2O42+ core, Mo2O2S2L2 have been prepared by addition of triphenylphosphine to a chloroform solution of Mo2OS3L2. While, Mo2OS3L2 is obtained from aqueous solution of (NH4)2MoS4 and ligand in the presence of sodium dithionite. The complexes are identified by elemental analysis, and spectral data of IR, UV-vis, nmr, and mass. Also, the electrochemical behaviour for the complexes in dimethylsulfoxide has been investigated by the cyclic voltammograms.
