1. The problem statement, all variables and given/known data Given that the primitive basis vectors of a lattice area (a/2)(I+J),(a/2)(j+k), (a/2)(k+i), where I j and k are the usual three unit vectors along Cartesian coordinates, what is the bravais lattice? 2. Relevant equations 3. The attempt at a solution So just drawing the three vectors given gives the obvious. The first is on the z-origin and makes a 45 degree angel between the x and y axis's. The second vector is on the x-origin and makes a 45 degree angel between the y and z azis. The third vector is on the y-origin and makes a 45 degree angel between the z and x axis. How do I use these three lines to identify the type of bravais lattice?
