Abstract
Solvothermal syntheses and X-ray crystal structures of two phosphates [GaP2O7(OH)][NH3(CH2) 3NH3] (1) and [Ge0.5GaP1.5O 6.5(OH)1.5][NH3(CH2) 3NH3] (2) are presented. Both structures are built up from GaO4 and PO4 tertrahedra or GeO4, GaO 4 and PO4 tertrahedra which form chain along the crystallographic c-axis. These chains are interconnected by 1,3-propanediamine molcules. Crystal data for 1: Mr = 331.82, space group P-1, a = 0.8303(2) nm, b = 0.8614(3) nm, c = 0.8880(2) nm, α = 111.70(3)°, β = 107.59(2)°, γ = 98.39(2)°, V = 0.5382(3) nm3, Z = 1, Mo Kα, λ = 0.071073 nm, R(F) = 5.56%, wR(F2) = 14.36% for 202 parameters and 3136 reflections with I>σ(I). Crystal data for 2; Mr = 358.13, space group P2(1)/c, a = 0.88968(7) nm, b = 1.67562(13) nm, c = 0.83666(7) nm, β = 115.890(2), V = 1.12208(16) nm 3, Z = 4, Mo Kα, R(F) = 4.66%, wR(F2) = 10.10% for 212 parameters and 1612 reflections with I>2σ(I).
