1967Office of Naval Res. Aerojet-General Corp. Techn. Rep. No. 15. 1 Until very recently,..the only good method of synthesizing these closo-compounds was via the nido-carborane, C2B4H8 . 1968[see *closo a.]. 1971Inorganic Chem. X. 214/2 All these structures may also be derived from the parent polyhedral series by a similar repetition of the process by which the nido structures..were generated from the closo structures. 1976Adv. Inorg. Chem. & Radiochem. XVIII. 4 There are three main structural types, closo, nido and arachno. 1980Chem. in Brit. Nov. 596/1 It is probable that open-cage, ie nido, species are involved in the growing of the BCl into the observed BnCln polymers. 1984Greenwood & Earnshaw Chem. of Elements (1986) vi. 185 Nido-boranes have the formula BnHn+4 . |
