Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated.
Non-combustible, substance itself does not burn but may decompose upon heating to produce irritating, corrosive and/or toxic fumes.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use water spray, fog or regular foam.

---

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation. Do not get water inside containers.

---

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Avoid breathing dust, vapor, mist, or gas. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Do not allow contact with water. Use only in a chemical fume hood. Keep from contact with moist air and steam.
Storage:
Store in a tightly closed container. Keep under a nitrogen blanket.
Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from moisture.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.

  日期：——

  Reactions of R1GeCl3 (R1 = CMe2CH2COMe) with (Me3Si)2E (E = S, Se, Te) yield three new organogermanium chalcogenide complexes [(R1GeCl)2S2] (1), [(R1GeCl)2Se2] (2), and [(R1GeCl)2Te2] (3) with functionalized ligands R1 = CMe2CH2COMe. NMR titration experiments clearly demonstrate that these dimeric complexes are intermediates in the formation of the well-known sesquichalcogenide clusters [(R1Ge)4E6]

  R 1 GeCl 3（R 1 = CMe 2 CH 2 COMe）与（Me 3 Si）2 E（E = S，Se，Te）的反应产生了三个新的有机锗硫属化物配合物[（R 1 GeCl）2 S 2 ]（1），具有官能化配体R 1 = CMe 2 CH 2的[（R 1 GeCl）2 Se 2 ]（2）和[（R 1 GeCl）2 Te 2 ]（3）来。NMR滴定实验清楚地表明，这些二聚体配合物是形成众所周知的倍半硫属化物簇[（R 1 Ge）4 E 6 ]的中间体。与最近报道的相关锡化合物形成鲜明对比的是，“ [（R 1 GeCl 2）2 E]”型单桥复合物和缺陷杂古巴型簇“ [（R 1 Ge）3 E 4 Cl对于E = S或Te，不会在NMR时间标度上形成，而仅在E = Se的痕迹中形成。
