چکیده
The cations and anions of the chiral title compound, C(5)H(14)N(2) (2+)·2Cl(-)·0.42H(2)O, are linked by N-H⋯Cl hydrogen bonds into chains propagating in [100], which contain R(4) (2)(14) loops.

Synthesis of chiral macrocyclic or linear pyridine carboxamides from pyridine-2,6-dicarbonyl dichloride as antimicrobial agents.
A series of chiral linear and macrocyclic bridged pyridines has been prepared starting from pyridine-2,6-dicarbonyl dichloride (2). The coupling of 1 with D-alanyl methyl ester gave 2,6-bis-D-alanyl pyridine methyl ester (3). Hydrazinolysis of 3 with hydrazine hydrate afforded bis-hydrazide 4. The latter was reacted with thiophene-2-carbaldehyde, phthalic anhydride or cyclohexanone to afford bi...
متن کاملSynthesis of new macrocyclic polyamides as antimicrobial agent candidates.
A series of macrocyclic imides and Schiff-bases have been prepared via the cyclocondensation of pyridine-2,6-dicarbonyl dichloride (1) with L-ornithine methyl ester to give the corresponding macrocyclic bisester 2. Treatment of 2 with hydrazine hydrate gave macrocyclic bisacid hydrazide 3, which was used as starting material. Condensation of bishydrazide 3 with diacid anhydrides or aromatic ald...

In the title salt hydrate, C(22)H(30)N(2)O(6) (2+)·2Cl(-)·CH(4)O, the dication adopts a U-shaped conformation whereby the benzene rings are splayed out from the chain linking them. All components of the asymmetric unit are linked into a cohesive entity by a combination of O-H⋯Cl(-), N(+)-H⋯Cl(-) and N(+)-H⋯O charge-assisted hydrogen-bonding inter-actions. The assemblies thus formed are linked i...

The carbene adducts 3a-c (R 1 = Me, Et, iso-Pr; R2 = Me) are formed from the 2,3-dihydroimidazol-2-ylidenes la-c and 1,2-dichloroethane as air-sensitive solids in good yields. The compounds exhibit a reactive Cl-Cl bond. Benzene is chlorinated by 3a,b to give chlorobenzene and the imidazolium salts 10a,b under mild conditions. 3c acts as a chloride donor to give with AICI3 and S 0 2 the 2-chlor...
متن کاملcatena-Poly[(S)-2-methylpiperazine-1,4-diium [[trichloridobismuthate(III)]-di-μ-chlorido]]
In the crystal structure of the title compound, {(C(5)H(14)N(2))[BiCl(5)]}(n), the Bi(III) cation is coordinated by six Cl(-) anions in a distorted octa-hedral geometry. Two Cl(-) anions bridge neighboring Bi(III) cations, forming a zigzag polymeric chain along the a axis. The discrete methylpiperazinediium cation adopts a normal chair conformation and is linked to the polymeric chains by N-H⋯C...
