Photoinduced dissociation of two Mo-CN bonds in [Mo(CN)8]4- affords the octahedral complex anion [Mo(CN)6]2-. This hexacyanomolybdate(IV) ion is also obtainable from tetracyanooxomolybdate via a thermal substitutional synthetic route. The anion represents the missing link in the ligand-field photolysis of octacyanomolybdate(IV); it is characterized by means of single-crystal X-ray diffraction, thermogravimetric analysis, and magnetic susceptibility measurements as well as IR, Raman, 1H and 13C NMR, and electronic spectroscopy.

The aim of this article is to analyse the experiences gained by tourists visiting one of the most visited protected areas in Poland—the Tatra National Park (TNP). The authors focused on the following question: does the natural heritage of the national park affect visitors’ unique experiences or is environmentally valuable area not important for their experiences? This article uses mixed quantitative (Text Mining, co-occurrence network analysis) and qualitative (narratives research) methods. Data for analysis—revives posted by users between April 2011 and September 2019—were downloaded from TripAdvisor.co.uk. Reviews on TripAdvisor indicate that the most important for visiting tourists were the experiences of physical activity. This confirms the trend of maintaining health and the desire to regenerate physical strength. The group of reviews related to connection to nature experiences is extremely small, which indicates that tourists probably did not come to TNP as a result of a preference for experiences related to ecological awareness. Some tourists felt tension, which indicates that the carrying capacity was exceeded. There is a doubt as to whether tourists who want to engage in physical activity must necessarily visit the area with the highest degree of nature protection.

The aim of the article is to analyze the relationship between lifestyle changes and willingness to use sharing economy services in tourism, including peer-to-peer accommodation. On the one hand, knowledge of lifestyle changes can help adapt the product offer to the requirements of consumers. On the other hand, products that consumers use can reflect lifestyle changes. The following classification of motivations for sharing economy activity selection resulting from the subjects’ lifestyles has been proposed: personal motivations—related to economic advantages; social (conformist) motivations—resulting from the need to fit in with others; and ideological motivation—resulting from the understanding of the processes of natural environment degradation and excessive consumption. In order to gather opinions and to understand behaviors, attitudes, and preferences regarding sharing economy activities (i.e., the sharing of transportation, food, clothes, equipment, and accommodation), the focus group interview method was used (6 groups, 5–8 participants each). Discussions were conducted separately for two populations: young with time (YT) and older rich (OR). The study demonstrates lifestyle changes between the generations. YT actions are the consequence of personal and ideological motivations. OR have lifestyles that result from personal and conformist motivations. Neither population sees a relationship between participating in the sharing economy and caring for the environment and preventing excessive consumption.

Tourist attractiveness of many areas in Poland is based on exceptional natural values, especially those protected by national parks. Recreation opportunities offered by national parks proved to be important during the COVID-19 pandemic, when the conditions for tourism changed. Many tourists gave up previously planned trips abroad in favour of staying in Poland. This raises the question whether tourists visiting national parks during the pandemic rested in compliance with the principles of sustainable tourism. The article is an attempt to diagnose changes caused by the influence of the COVID-19 pandemic on sustainable tourism by analysing the case of national parks in Poland. The article presents: a) a diagnosis of changes triggered at different stages of restrictions introduced by the government to prevent the spread of the pandemic; b) a forecast of how the pandemic may affect the development of tourism in terms of supply (tourist companies, hotels, catering, attractions) and demand (tourists). The summary provides recommendations for national parks, which can be helpful in achieving sustainable tourism objectives.
