A very useful tool to produce continuous degrees of strength is pressure, since it allows altering interatomic distances with much better accuracy and cleanliness than playing with atomic composition. Pressure is the perfect tool to distinguish between the pre-MMB and MMB scenarios. The importance of applying high pressure (HP) to understand the unconventional bond present in PCMs has been highlighted in several works . Unfortunately, the importance of pressure has not been fully exploited despite examples of the pressure-induced MMB formation in IV-VI and V2-VI3 chalcogenides, such as GeSe, SnSe, GeTe, and As2S3 , have been published. In particular, it has been shown how the change from the pre-MMB scenario towards the MMB scenario proceeds as octahedral coordination is approached at HP. In this context, it has been stressed that more HP studies, in particular computational ones, are needed to understand the effect of pressure on MMBs, exploring the bond strength-bond length relation in the pre-MMB scenario and how pressure affects the deviation from octahedral coordination in this scenario . Notwithstanding, a systematic study of the pressureinduced MMB formation in elemental pnictogens and in IV-VI and V2-VI3 chalcogenides has not been undertaken yet.
