Sila-Chlorphencyclan (8b), ein Sila-Analogon des Chlorphencyclans (8a), die Derivate 7 und 9, deren Ammoniumsalze 11, 12, 13 und 14b, das Hydrolyseprodukt 10 sowie die Vorstufen 3-6 wurden erstmalig dargestellt. Die neuen Verbindungen wurden in ihren chemischen und physikalischen Eigenschaften charakterisiert, ihre Struktur wurde sichergestellt. Chlorphencyclan, Sila-Chlorphencyclan und einige seiner Derivate wurden vergleichend pharmakologisch und toxikologisch untersucht.

NH4CuS4 was prepared according to syntheses reported in the literature. Orthorhombic crystals could be grown (P21 21 21 , a = 5.249(1), b = 8.444(2), c = 12.782(2) A, Z = 4), the structure of which was solved from X-ray diffractometer data. (R = 0.031 for 767 obs. reflections). In the solid state (CuS4)- chelate rings are linked via additional Cu-S-bonds to form one-dimensional polymerie anions.

A substantial literature exists on the coordination of speaking and looking behaviour and their significance as indicators for the production and reception of social information. Within this framework, the temporal organisation of such behaviour has been 'shown to reflect both the coordination within the individual and between participants in a situation. In this paper, it is proposed that observed behavioural sequences may be formally described by rules of syntax, thus implying the likelihood of structural organisation as opposed to, for example, linear time dependence between behavioural states. This being the case, differing sets of rules and grammars respectively can be expected for various social situations. Clinical interviews and discu~sions between couples on a topic of marital conflict were analysed, the on-off patterns of speech and gaze being taken as data. The resulting behavioural repertoire was regarded, in the sense of a formal grammar, as the terminal vocabulary. A set of rewriting rules was determined and their associated probabilities inferred. The situational conditions were found to be reflectedin the syntactic features of the grammatical model - the terminal vocabulary, the production rules and the production probabilities.
