| Abstract: | A P? N compound XI, formula see ?Inhaltsübersicht”?, has been prepared containing three interconnected four-membered rings. On chlorination of XI P2(NCH3)2Cl6 is re-formed, besides a further product being very probably compound XII with hexa-coordinated phosphorus. Interaction between the known Cl4P(NCH3)2 CCl2 and NN′-dimethyl urea yields III and another compound, VII, with phosphorous of coordination number six. |
