Abstract
The chemical preparation, the calorimetric studies and the crystal structure are given for two new organic sulfates NH3(CH2)5NH3SO4 1.5H2O (DAP-S) and NH3(CH2)9NH3SO4·H2O (DAN-S). DAP-S is monoclinic P21/n with unit cell dimensions: a=11.9330(2) Ã
; b=10.9290(2)Â Ã
; c=17.5260(2)Â Ã
; β=101.873(1)°; V=2236.77(6) Ã
3; and Z=8. Its atomic arrangement is described as inorganic layers of SO42â units and water molecules separated by organic chains. DAN-S is monoclinic P21/c with unit cell parameters: a=5.768(2)Â Ã
; b=25.890(10)Â Ã
; c=11.177(5)Â Ã
; β=115.70(4)°; V=1504.0(11) Ã
3 and Z=4. Its structure exhibits infinite chains, parallel to the [100] direction where the organic cations are interconnected. In both structures a network of strong and weak hydrogen bonds connects the different components in the building of the crystal.
