A Medley of Potpourri: Mercury (element -- updated)
It has a freezing point of −38.83 C and a boiling point of 356.73 C, both the lowest of any stable metal, although preliminary experiments on copernicium and flerovium have indied that they have even lower boiling points (copernicium being the element below mercury in the periodic table, following the trend of decreasing boiling points down group 12).
A Medley of Potpourri: Antimony
Four allotropes of antimony are known: a stable metallic form and three metastable forms (explosive, black and yellow). Elemental antimony is a brittle, silver-white shiny metalloid.When slowly cooled, molten antimony crystallizes in a trigonal cell, isomorphic with the gray allotrope of arsenic..

The metal‐organic framework CAU‐17 is the first bismuth MOF synthesized from cheap starting materials. Its properties were investigated with in‐situ PXRD (fast crystallization), thermodiffraction (shrinking unit cell upon heating), N 2 /CO 2 /SF 6 sorption (high selectivity) and by using CAU‐17 as alyst in the ring opening reaction of styrene oxide.

The extracellular domain of rat P 0 crystallizes under near physiological conditions. This fact, along with data from analytical ultracentrifugation and electron microscopy, strongly supports the proposal that the two types of molecular contacts observed in crystals of P 0 correspond to two modes of interaction involved in the cell adhesion function of P 0 ( 64 ).
