Separation of a nickel(II)–rubeanic acid complex prepared on interlamellar surfaces of molybdenum trioxide

Abstract

A stable Ni^II–rubeanic acid co-ordination polymer prepared in the interlayer space of MoO₃ has been separated by dissolving the MoO₃ layers. The molecular structure of the separated complex has been examined by chemical analysis, thermogravimetry, i.r. spectroscopy, and magnetic measurements, and the structure and properties compared with those of a Ni^II–rubeanic acid co-ordination polymer prepared by the usual precipitation method. It is concluded that the two methods of preparation result in different forms of the nickel complex.
