四水合物分析。四季。： c, 38.40；H, 4.26;N, 7.47;有限公司15.75。发现：C， 38.45, 38.60；， 4.01, 3.93；N, 7.84, 7.84；公司，15.70,15.84。当让粉红色的晶体暴露在空气中时，它们慢慢地吸收水分，从粉红色变回黄橙色。它们不会吸收氧气。7. (钴Di) - o-aminobenzal -ethylenediimine。-在乙醇和二恶烷的混合物中，将氨基苯甲醛和乙二胺混合制备希夫碱。在希夫碱热溶液中加入醋酸钴热水溶液。形成了一种很好结晶的未溶剂化的红色产物。所有用吡啶等溶剂化它的努力都是徒劳的。这种化合物不吸收氧气。四季。： c, 59.45；H, 4.96;N, 17.34;有限公司18.27。发现：C， 59.28, 59.28；H, 4.66, 4.56；N, 17.89, 18.09；17.8, 17.3。8. CobaltNaphthazarin(聚合物)。-用乙醚提取多余的萘扎酚。四季。： c, 42.4；h . 2.83;有限公司20.85。发现：C， 41.5, 41.5；， 3.00, 3.07；Co, 20.3, 20.2。当加热时，样品的重量损失10.0%，称为2h2o /钴为12.7%。溶解后从空气中缓慢吸收水分。9. 钴Di - (1 - (o-hydroxyphenyl)异喹啉)。-在除去水合水后，以一水合物的形式沉淀，对氧气是惰性的。
Analysis of tetrahydrate. Caled.: C, 38.40; H, 4.26; N, 7.47; Co, 15.75. Found: C, 38.45, 38.60;, 4.01, 3.93; N, 7.84, 7.84; Co, 15.70, 15.84. When allowed to stand opento air the pink crystals slowly absorbedwater and changed from pink back to yellow-orange. They would not absorb oxygen. 7. Cobalt Di-(o-aminobenzal)-ethylenediimine.—The Schiff base was prepared by mixingo-aminobenzaldehyde and ethylenediamine in a mixture of ethanol and dioxane. To this hot solution of Schiff base was added a hot aqueous solution of cobaltous acetate. A nicely crystallized red product was formed which was unsolvated. All efforts to solvate it with pyridine, etc., were in vain. The com-pound would not take up oxygen. Caled.: C, 59.45; H, 4.96; N, 17.34; Co, 18.27. Found: C, 59.28, 59.28; H, 4.66, 4.56; N, 17.89, 18.09; Co, 17.8, 17.3. 8. CobaltNaphthazarin (Polymer).—Excess naphthazarin was extracted off with ether.Anal. Caled.: C, 42.4; H. 2.83; Co, 20.85. Found: C, 41.5, 41.5;, 3.00, 3.07; Co, 20.3, 20.2. When heated a sample lost 10.0% in weight, caled, for 2H20 per cobalt is 12.7%. Slowly absorbswater from the air following desolvation. 9. Cobalt Di-(1-[o-hydroxyphenyl]-isoquinoline).—Precipitates as a monohydrate which is inert to oxygen after removal of the hydrated water.
