چکیده

There are two cation-dianion pairs in the asymmetric unit of the title compound, C(21)H(27)ClN(2)O(3) (2+)·2C(6)H(2)N(3)O(7) (-) {systematic name: 1-[2-(carb-oxy-meth-oxy)eth-yl]-4-[(R)-(4-chloro-phen-yl)phenyl-meth-yl]piperazine-1,4-diium bis-(2,4,6-trinitro-phenol-ate)}. The piperazine group in the levocetirizinium cation is protonated at both N atoms. The acetyl end groups form R(2) (2)(8) hydrogen-bonded motifs with adjacent cations. Each picrate anion inter-acts with the proponated N atom in the cation through a bifurcated N-H⋯O hydrogen bond, forming R(1) (2)(6) ring motifs. Strong and weak inter-molecular N-H⋯O and strong O-H⋯O hydrogen bonds, and weak π-ring and π-π stacking inter-actions [centroid-centroid distance = 3.7419 (14) Å] dominate the crystal packing, creating a three-dimensional supra-molecular structure.

In the title compound, [Cd(C(22)H(26)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·C(3)H(7)NO, the Cd(II) ion is coordinated by four N atoms and two O atoms from two tridentate 1,3-bis-(1-propyl-1H-benzimidazol-2-yl)-2-oxopropane ligands in a distorted octa-hedral coordination environment. There are significant differences in the chemically equivalent Cd-O bond lengths [2.618 (2) Å and 2.561 (2) Å].

Bis[N,N-bis­(1-allyl-1H-benzimidazol-2-ylmethyl-κN 3)benzyl­amine-κN]cadmium dipicrate

The crystal structure of the title compound, [Cd(C(29)H(29)N(5))(2)](C(6)H(2)N(3)O(7))(2), consists of Cd(II) complex cations and picrate anions. In the complex cation, the Cd(II) ion is chelated by two bis-(1-allyl-benzimidazol-2-ylmeth-yl)benzyl-amine (babb) ligands in a distorted octa-hedral geometry. Extensive C-H⋯O hydrogen bonding occurs between cations and anions in the crystal structure.
