The cobalt(II) complexes are high-spin and five-co-ordinate, probably trigonal bipyramidal, both in the solid state and in solution. The [NiLX]BPh4 complexes with L =(I), X = l or NCS are low-spin and probably five-co-ordinate in the solid state with a distorted square-pyramidal stereochemistry. All the other nickel complexes are thought to have a square-planar structure with the ligand L being terdentate with an NNP donor set. The complex [Ni(NOAs2)l]BPh4 derived from the ligand NN-bis-(2-diphenylarsinoethyl)-2-methoxyethylamine (III; donor set NOAs2) is accorded a five-co-ordinate, ‘elongated’ square-pyramidal structure.","PeriodicalId":17321,"journal":{"name":"Journal of The Chemical Society A: Inorganic, Physical, Theoretical","volume":"79 1","pages":"1487-1491"},"PeriodicalIF":0.0,"publicationDate":"1971-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84086428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
