The title compound, C(8)H(18)N(4)O(2) (2+)·2Cl(-), contains two oxime groups. The methyl oxime group has a Z configuration, and the ethyl oxime group is disordered, with both Z and E configurations in occupancies of 0.840 (8) and 0.160 (8), respectively. In the crystal structure, there are a number of N-H⋯Cl hydrogen bonds.
متن کاملBis(3-azaniumylpyridin-1-ium) hexachloridostannate(IV) dichloride
The asymmetric unit of the title compound, (C5H8N2)2[SnCl6]Cl2, consists of one 3-aza-niumylpyridin-1-ium dication and one chloride ion in a general position and a hexa-chloridostannate(IV) dianion lying about a centre of inversion. The [SnCl6](2-) anion exhibits almost perfect octa-hedral geometry. The 3-aza-niumylpyridin-1-ium and chloride ions are connected via medium-strong charge-supported...
متن کامل2-Amino-3-carboxypyrazin-1-ium perchlorate bis(2-aminopyrazin-1-ium-3-carboxylate) monohydrate
The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-)·2C(5)H(5)N(3)O(2)·H(2)O, comprises two symmetry-independent zwitterions, one cation, one perchlorate anion and one water mol-ecule. In the crystal, the three different types of organic entities are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming undulating sheets parallel to (1-10). These sheets are in turn connected b...
متن کامل1-[Bis(4-fluorophenyl)methyl]-4-[(2Z)-3-phenylprop-2-en-1-yl]piperazine-1,4-diium dichloride hemihydrate
The asymmetric unit of the title monohydrated salt, 2C26H28F2N2 (2+)·4Cl(-.)H2O, consists of a 1-[bis-(4-fluoro-phen-yl)meth-yl]-4-[(2Z)-3-phenyl-prop-2-en-1-yl]piperazine-1,4-diium cation with a diprotonated piperizine ring in close proximity to two chloride anions and a single water mol-ecule that lies on a twofold rotation axis. In the cation, the piperazine ring adopts a slightly distorted ...
