and chemical studies. The reaction of [Ru(NO)2(PPh3)2] with SO2 proceeds in a quite different fashion and gives an SO2 adduct [Ru(NO)2(PPh3)2(SO2)] which has both a linear and a bent NO ligand. This complex is readily oxidised to the corresponding sulphato-complex in air.

Toxic organicpollutants have a severe impact on the environment as well as the living organisms around the world. Surface-enhanced Raman spectroscopy (SERS) is considered to be the advanced sensing strategy for the ultrasensitive detection of organicpollutants. Herein, a novel octahedral Ag2SO3microcrystal was synthesised using the silver-ammonia complex precipitation method for the detection of
有毒有机污染物对环境以及世界各地的生物都造成严重影响。表面增强拉曼光谱(SERS)被认为是有机污染物超灵敏检测的先进传感策略。在此,使用银-氨络合物沉淀法合成了一种新型八面体Ag 2 SO 3微晶,用于检测除草剂(4-氯苯酚)和合成染料(日落黄和亚甲蓝染料)。Ag 2 SO 3微晶具有约10 8量级的增强因子(EF),表现出优异的灵敏度。Ag 2 SO 3具有粗糙八面体形态的大表面积有利于形成丰富的热点。所制备的Ag 2 SO 3还具有优异的可回收性,可通过光照射归因于化学增强。还研究了 Ag 2 SO 3检测 4-CP 对河水和蜂蜜干扰的能力。根据结果推测,Ag 2 SO 3微晶是可重复使用的 SERS 应用的有前途的基材。

The reaction of [Pt(NSO)2(PMe2Ph)2] with water in dichloromethane gives the compounds [Pt(SO3)(PMe2Ph)3].H2O 1 and [Pt(SO3)(PMe2Ph)2}2].5CHCl3 2 which have been characterised by multielement NMR spectroscopy and X-ray crystallography. The mononuclear compound 1 has tetrahedrally distorted square-planar co-ordination of the platinum by three phosphines and the sulfur atom of the sulfite with trans angles of 160.4(1) and 161.2(1)-degrees. The binuclear complex 2 contains a six-membered Pt2S2O2 ring in a chair conformation with each platinum being co-ordinated by two phosphines and a sulfur and oxygen atom of the different SO3(2-) ligands. Phosphorus-31 NM R studies show that the reaction of Ag2SO3 with [PtCl2(PR3)2] gives 1 and 2 or simple, O,O' complexes depending on the nature of PR3.
