Two new organo-phosphate and organo-sulfate compounds were synthesized at room temperature. They have been firstly characterised by X-ray diffraction (XRD)—C 6 H 5 CH 2 C 5 H 4 NH + ·H 2 PO 4 − is monoclinic P 2 1 / c with following unit cell dimensions: a = 5.7950(3) A, b = 9.3490(18) A, c = 23.537(5) A and β = 97.328(11)°. C 6 H 5 CH 2 C 5 H 4 NH + ·HSO 4 − is monoclinic P 2 1 / a with following unit cell dimensions: a = 8.990(6) A, b = 9.925(7) A, c = 14.081(9) A and β = 105.18(8)°. In both cases the structure consists of infinite parallel two-dimensional planes built of mutually H 2 PO 4 − /HSO 4 − anions and C 6 H 5 CH 2 C 5 H 4 NH + cations connected by strong O–H⋯O and N–H⋯O hydrogen bonds. Then, in order to detect phase transitions and watch changes in the conductivity behaviour, investigations by differential scanning calorimetry (DSC), electrical conductivity measurements were carried out. A substitution of H 2 PO 4 − by HSO 4 − increases the conductivity even at room temperature. |
