Abstract
MoCl5와 NaNO2 및 산성화시킨 FeSO4의 reductive nitrosylation 반응을 통해 다핵 화합물인 [{Mo(NO)2Cl2}n]을 합성하였다. 이 [{Mo(NO)2Cl2}n]와 한자리 및 두자리 리간드를 반응시켜 높은 수득률(80∼90%)로 중성의 단핵 화합물인 [Mo(NO)2Cl2L2(or L-L)]을 얻었다. 사용한 리간드는 3,5-Lutidine, γ-Cyanopyridine, 1,2-Phenylenediamine, 1,10-Phenanthroline, sym-Diphenylethylenediamine, 9,10-Phenanthrenequinone, 1,3-Bis(diphenylphosphino)propane 및 8-Hydroxyquinoline 이였다. 합성한 dinitrosylmolybdenum 착물은 원소분석과 적외선, 핵자기 공명 및 전자 흡수 스펙트럼 등을 이용해서 그 특성을 조사하였다. 적외선 스펙트럼은 모든 화합물이 팔면체 구조로서 두 개의 NO 기가 cis 위치로 배위되어 있음을 보였다.

The polymeric compound [{Mo(NO)2Cl2}n] was prepared by reductive nitrosylation of NaNO2 and acidified FeSO4 with MoCl5. The reactions of [{Mo(NO)2Cl2}n] with unidentate and bidentate ligands afforded neutral monomeric [Mo(NO)2Cl2L2(or L-L)] in high yield (80∼90%). 3,5-Lutidine, γ-Cyanopyridine, 1,2-Phenylenediamine, 1,10-Phenanthroline, sym-Diphenylethylenediamine, 9,10-Phenanthrenequinone, 1,3-Bis(diphenylphosphino)propane and 8-Hydroxyquinoline were used as coordinating ligands. The preparation and characterization of these dinitrosylmolybdenum complexes by elemental analysis, 1H NMR, infrared, and UV-Visible spectroscopy are reported. The infrared spectra indicate that in all of the compounds prepared, the NO groups occupy cis-positions in the octahedral group of ligands.
