Bucher, J; Blacque, O; Schmalle, H W; Berke, H (2008). Bis(glycinato-kappa2N,O)dinitrosylmolybdenum(0) and bis(2-aminoethanethiolato-kappa2N,S)dinitrosylmolybdenum(0) acetonitrile monosolvate. Acta Crystallographica. Section C, Crystal Structure Communications, 64(2):M87-M90.

Abstract

The title compds., [Mo(C2H4NO2)2(NO)2], (I), and [Mo(C2H6NS)2(NO)2]CH3CN, (II), contain distorted octahedral complexes in which the monoanionic N,S- and N,O-bidentate ligands coordinate the molybdenum centers in different modes. The anionic O atoms of the glycinate ligands in (I) are coordinated trans to the nitrosyl ligands and the amine N atoms are located trans to each other, whereas in (II) the anionic S atoms are coordinated trans to each other and the amine N atoms are located trans to the nitrosyl ligands. Each compd. has a single complete complex in the asym. unit on a general position. Six N-HO contacts with NO distances of less than 3.2 .ANG. are obsd. in (I) between the amine groups and the nitrosyl and carboxylate O atoms. In the 1:1 solvate (II), the acetonitrile mol. forms short N-HN contacts (NN < 3.2 .ANG.) between the solvent N atoms and one of the amine H atoms. In addn., three weak intermol. N-HS interactions (NS > 3.3 .ANG.) contribute to the stabilization of the structure of (II)

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
