to one side of the cavity so that is it more coordinated with oxygen than its other side. Gatehouse et al., 1974 described the four remaining hydrogen as being in a chain and contributing to the complexity of the structure but Gatta et al., 2013, gives a well define H-bonding scheme and how these hydrogen items confines in OH groups. One of the hydrogen in brazilianite splits to make a fifth hydrogen. The splitting of this hydrogen has not been explained why it happens but it was shown that it can affect the hydrogen bond configuration. Some of the oxygen atoms in the four OH groups in brazilianite act as donors and some as acceptors of the hydrogen bond. One of these oxygen items is both a donor and acceptor to accommodate the hydrogen that split into two. Physical properties Brazilianite is a mineral in the monoclinic system that is part of the point group 2/m and belongs to the space group P21/n. The crystals of brazilianite are elongated and prismatic along [100]. Most common forms that are measured in brazilianite {010}, {110}, { 11}. It displays a perfect cleavage on (010), it is brittle and has a conchoidal fracture. The mineral has a Mohs hardness of 5.5 and was believed it had a specific gravity of 2.94 which was first determined by Pough and Henderson, 1945. With the second occurrence of the mineral, it was determined that the specific gravity of the mineral was actually 2.98. Brazilianite has a vitreous luster, has a white streak, and the mineral is translucent to transparent. The color of brazilianite ranges from dark yellow-green to a pale yellow. Brazilianite begins to lose its color when heated to 200 °C and becomes colorless when it is heated to 300 °C. Geological occurrence Brazilianite is typically found in granite pegmatite and it is often found the cavities within the pegmatite where quartz, beryl and mica are also found. Different habits of brazilianite have been found in different locations. Brazilianite is often found with muscovite. The Corrego Frio pegmatite where brazilianite is found in Brazil is an altered pegmatite dike that had weathered biotite schist between its walls. In New Hampshire, the pegmatite where the brazilianite was found was made up of 99 percent albite, mica, and quartz. Brazilianite also found with tourmaline and feldspar.
