摘要：
Chemical preparation, X-ray single-crystal of the bis(2-aminopyridinium)-dihydrogendiphosphate monohydrate (C5H7N2)(2)H2P2O7 center dot H2O are described. The title compound crystallizes in the triclinic system with P (1) over bar space group. The unit cell dimensions are a = 8.4378(4) angstrom, b = 8.5567(4) angstrom, c = 12.3245(5) angstrom, alpha = 105.678(2)degrees, beta = 94.503(3) angstrom, gamma = 104.885(3)degrees with V = 817.44(6) angstrom(3) and Z = 2. The structure of this compound includes two types of hydrogen bonds: (i) O-H center dot center dot center dot O, links the H2P2O7 groups to form infinite inorganic layers [H2P2O7(H2O)](n)(2n-) . in (101) plan, (ii) N-H center dot center dot center dot O assemble inorganic layers leading to a three-dimensional arrangement.
