Figure 1 Partial plot of (Ag0.79Co0.11)Co(H2O)2[BP2O8],0.67(H2O) crystal structure showing polyhedra linkage. Displacement ellipsoids are drawn at the 50% probability level. Symmetry codes: (i) -y + 1, -x + 1, -z + 13/6; (ii) y - 1, -x + y, z + [{1\over 6}]; (iii) y - 1, x, -z + [{5\over 3}]; (iv) x, x-y + 1, -z + 11/6; (v) -x + y - 1, y, -z + [{3\over 2}]; (vi) -x, -x + y, -z + 4/3; (vii) y, x + 1, -z + [{5\over 3}]; (viii) x-y + 1, -y + 2, -z + 2.  [article HTML]
