Selanylidenenickel typically appears as a dark crystalline solid with metallic luster at room temperature. The compound has a molecular weight of 137.66 g/mol and exhibits semiconductor properties characteristic of transition metal selenides. It is generally insoluble in water but may react with strong acids. The material demonstrates stability under normal conditions but requires careful handling due to its toxic nature. Its crystal structure and electrical properties make it suitable for specialized electronic applications.

Selanylidenenickel is primarily used in specialized electronic and semiconductor applications due to its unique electrical properties. It serves as a component in certain photovoltaic cells, electronic devices, and research applications involving transition metal selenides. The compound may also be utilized in catalysis research and materials science studies. Given its hazardous classification, its use is typically restricted to professional and industrial settings with appropriate safety controls and expertise in handling toxic materials.

Selanylidenenickel requires extreme caution due to its carcinogenic and sensitizing properties. Essential personal protective equipment includes respiratory protection with appropriate filters, chemical-resistant gloves, safety goggles, and protective clothing covering all exposed skin. Work must be conducted in well-ventilated areas, preferably under fume hoods or controlled atmospheres. Avoid generating dust or vapors, and never eat, drink, or smoke in work areas. Regular health monitoring and training in hazardous material handling are essential for all personnel.

Selanylidenenickel must be stored in tightly sealed, chemically compatible containers in a cool, dry, well-ventilated area away from incompatible materials. Storage areas should be restricted to authorized personnel only, with appropriate warning signage and secondary containment measures. Keep away from sources of heat, sparks, and direct sunlight. The storage facility should have emergency response equipment readily available and comply with local regulations for carcinogenic substances. Regular inventory checks and container integrity inspections are recommended.

Immediate decontamination is crucial following any contact with selanylidenenickel. For skin contact, remove contaminated clothing and wash affected areas thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, flush with clean water for 15 minutes and remove contact lenses if present. In all cases of exposure, seek immediate medical attention and inform healthcare providers about the carcinogenic nature of the substance and potential for sensitization.

Selanylidenenickel disposal must comply with local and international hazardous waste regulations due to its carcinogenic and environmentally toxic properties. The material cannot be disposed of through regular waste streams and requires specialized hazardous waste treatment facilities. Contact licensed hazardous waste disposal companies with experience in heavy metal and carcinogenic compounds. Maintain detailed disposal records and certificates of destruction. Never attempt to neutralize, dilute, or dispose of the material without proper authorization and expertise.

Selanylidenenickel is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. Packages must be properly labeled with appropriate hazard markings and documentation must include proper shipping names and hazard classifications. Vehicles transporting this material require appropriate ADR certification and drivers must have hazardous materials training. Emergency response information must accompany shipments, and transport should follow designated routes with appropriate emergency response capabilities available along the route.

Selanylidenenickel is subject to extensive European regulations including REACH registration requirements and CLP classification as a Category 1A carcinogen. While not currently listed as a Substance of Very High Concern (SVHC), its carcinogenic classification subjects it to strict occupational exposure limits and workplace controls. Users must comply with industrial emissions directives, waste framework regulations, and may require specific permits for use. Regular monitoring, risk assessments, and worker health surveillance programs are typically mandatory under occupational safety regulations.
