Crystal structures of 4-phenylpiperazin-1-ium 6-chloro-5-ethyl-2,4-dioxopyrimidin-1-ide and 4-phenylpiperazin-1-ium 6-chloro-5-isopropyl-2,4-dioxopyrimidin-1-ide
The title mol-ecular salts, C10H15N2 (+)·C6H6ClN2O2 (-), (I), and C10H15N2 (+)·C7H8ClN2O2 (-), (II), consist of 4-phenyl-piperazin-1-ium cations with a 6-chloro-5-ethyl-2,4-dioxopyrimidin-1-ide anion in (I) and a 6-chloro-5-isopropyl-2,4-dioxopyrimidin-1-ide anion in (II). Salt (I) crystallizes with two independent cations and anions in the asymmetric unit. In the crystal structures of both sal...

In the cation of the title salt, C11H17N2O(+)·C7H8ClN2O2 (-), the piperazine ring adopts a distorted chair conformation and contains a positively charged N atom with quaternary character. Its mean plane makes a dihedral angle of 42.36 (8)° with the phenyl ring of its 2-meth-oxy-phenyl substituent. The 2,4-dioxopyrimidin-1-ide anion is generated by deprotonation of the N atom at the 1-position o...

The title mol-ecule, C17H15ClN2O2, is L-shaped with the 4-chloro-benzyl-idene ring almost coplanar with the planar pyrazolidine ring (r.m.s. deviation = 0.020 Å), making a dihedral angle of 4.83 (17)°. The 4-meth-oxy-phenyl ring is almost normal to the mean plane of the pyrazolidine ring and the 4-chloro-benzyl-idene ring, with dihedral angles of 87.36 (17) and 89.23 (16)°, respectively. The py...

In the title compound, [Mg(H(2)O)(6)](C(8)H(6)N(5)O(2))Cl·2H(2)O, the Mg(II) ion is surrounded by six water mol-ecules, exhibiting a slightly distorted octa-hedral coordination. The pyridine and tetra-zole rings are nearly coplanar, forming a dihedral angle of 4.63 (3)°. The complex cations, zwitterionic organic anions, Cl(-) anions and uncoordinated water mol-ecules are connected by O-H⋯O, O-H...

In the title compound, C(14)H(23)N(2)O(2)S(+)·C(2)F(3)O(2) (-), the piperazine ring adopts a chair conformation. The crystal packing is stabilized by C-H⋯O and N-H⋯O hydrogen bonds between the cation and anion. The F atoms are disordered over two positions; the site occupancy factors are 0.55 (2) and 0.45 (2).
