The structures of seven compounds based on guanidinium cations, isolated sulfate anions, and additional organic cations and solvent molecules are reported. All seven compounds, (C(NH2)3)2(SO4) (1), (C(NH2)3)3(C5H6N)(SO4)2(2), (C(NH2)3)3(C5H6N)(SO4)2·H2O (3), (C(NH2)3)3(C5H6N)(SO4)2·CH3OH (4), (C(NH2)3)11(C5H6N)(SO4)6·2.5C2H5OH (5), (C(NH2)3)3(C6H16N)(SO4)2(6), and (C(NH2)3)2(C20H26N2O2)(SO4)2(7) crystallize without a center of symmetry, and are built of related motifs of six-membered ringsviahydrogen bonding of three guanidinium cations and three sulfate anions. These six-membered rings form extended sheets and frameworks through additional hydrogen bonding interactions. The presence of additional cations and solvent molecules in varying ratios add structural diversity by modifying the guanidinium sulfate frameworks, but retaining the acentricity of the structures. The study reveals a remarkable tendency for these guanidinium sulfate frameworks to crystallize without a center of symmetry, and furthermore, in polar or chiral space groups. This provides a potential pathway for the use of hydrogen bonding interactions to design structures having interesting physical or nonlinear optical properties.
Carbonyl and oxalyl bridged bis(l,5-diaminotetrazole)-based energetic salts

experimental part, p. 9097 - 9104 (2010/04/25)
High density energetic salts containing nitrogen rich cations and carbonyl- or oxalylbis(diamino-tetrazole) anions, which were obtained from cyanogen azide and hydrazine, were readily synthesized. In every case, a new family of energetic salts 3-14 were c

, (2008/06/13)
Guanidinium salts having the formula STR1 wherein R1 and R2 are linear alkyl residues, X is an anion, and n is 1 or 2, which possess excellent microbicidal properties, particularly against organisms which have become resistant against other active materials. Methods for preparation of the compounds and solutions containing same are disclosed.
