Guanidinium chlorochromate
In the title compound, guanidinium chloridotrioxidochrom-ate(VI), (CH(6)N(3))[CrClO(3)], both the cation and anion are generated by crystallographic mirror symmetry, with one O and one N atom and the Cr, Cl and C atoms lying on the mirror plane. The bond lengths in the guanidinium cation are inter-mediate between normal C-N and C=N bond lengths, indicating significant delocalization in this spe...
متن کاملGuanidinium 4-aminobenzoate
In the title compound, CH(6)N(3) (+)·C(7)H(6)NO(2) (-), the cation and anion lie on crystallographic mirror planes. The 4-amino-benzoate anion is almost in a planar conformation with a maximum deviation of 0.024 (2) Å for the N atom. The bond length in the deprotonated carboxyl group is inter-mediate between those of normal single and double Csp(2)=O bonds, indicating delocalization of the char...

In the title compound, CH(6)N(3) (+)·C(16)H(31)O(4)S(2) (-) [systematic name: guanidinium 2-(tetra-deca-noylsulfan-yl)ethane-sulfon-ate], each 2-(myristoyl-thio)-ethane-sulfonate ion displays hydrogen bonding to three guanidinium counter-ions, which themselves display hydrogen bonding to two symmetry-related 2-(myristoylthio)ethanesulfonate ions. Thus each cation forms six N-H⋯O bonds to neighb...
متن کاملGuanidinium 3-nitrobenzoate
The title compound, CH(6)N(3) (+)·C(7)H(4)NO(4) (-), an anhydrous guanidinium salt, shows a N-H⋯O hydrogen-bond network in which the guanidinium cation is involved in three cyclic R(2) (1)(6) hydrogen-bonding associations with separate carboxyl-ate O-atom acceptors. Further peripheral associations include a cyclic R(1) (2)(4) cation-anion inter-action, forming inter-linked undulating sheets in ...
متن کاملGuanidinium tetrabromidomercurate(II)
The Hg atoms in the crystal structure of the title compound, (CH(6)N(3))(2)[HgBr(4)], are tetra-hedrally coordinated by four Br atoms and the resulting [HgBr(4)](2-) tetra-hedral ions are linked to the [C(NH(2))(3)](+) ions by bromine-hydrogen bonds, forming a three-dimensional network. In the structure, the anions are located on special positions. The two different Hg⋯Br distances of 2.664 (1)...
