Abstract  

A module is extending relative to a module class in two different ways. The definition and general properties of such extending modules have been given in [3] and also in the case of specific classes of modules has been characterized. In this paper, we define weak extending modules in two different ways with respect to general classes of modules. We give the relations between extending and weak extending modules and characterize them.

A new tin dithiocarbamate containing sulphur bridges, di-μ-sulphidobis [bis(N,N-diethyldithiocarbamato)tin(IV)], has been isolated from the thermal decomposition of tetrakis(N,N-diethyldithiocarbamato)tin(IV). A dimeric structure is proposed on the basis of results from mass spectrometry, infrared spectroscopy, thermal analysis and vapour pressure osmometry.
