Molecular structure of the decamolybdodicobaltate(III) ion
Howard Tasker Evans Jr., John S. Showell
1969, Journal of the American Chemical Society (91) 6881-6882
When solutions of cobalt(II) ion and heptamolybdate ion (Mo₇O₂₄⁶⁻) are mixed in the presence of an oxidizing agent (such as bromine), Kurnakov, Hall, and others found that an emerald green complex is formed as the main product, namely, the heteropoly complex ion hexamolybdocobaltate(III), which forms salts such as (NH₄)₃[H₆CoMo₆O₂₄]·12H₂O. Friedheim...
Glaciation on the continental margin off New England
Richard M. Pratt, John Stevens Schlee
1969, Geological Society of America Bulletin (80) 2335-2341
The Pleistocene glacial limit in the marine environment off New England can be traced by plotting the seaward limit of abundant sandy gravel and the position of shoals. Maximum limit of the last glaciation was probably along an irregular line extending through Nantucket Shoals, across...
