Title: | Poly[piperazine-1,4-diium [μ(4)-chlorido-μ(3)-chlorido-tri-μ(2)-chlorido-chloridodicadmate(II)] monohydrate] | Authors: | Adib, Marwa El Glaoui, Meher Silva, Pedro Sidónio Pereira da Silva, Manuela Ramos Ben Nasr, Cherif |
Keywords: | single-crystal X-ray study; T = 293 K; mean (C–C) = 0.003 A°; R factor = 0.018; wR factor = 0.045; data-to-parameter ratio = 23.9 | Issue Date: | 1-Feb-2012 | Publisher: | International Union of Crystallography | Project: | SFRH/BD/38387/2008 | Serial title, monograph or event: | Acta Crystallographica Section E: Structure Reports Online | Volume: | 68 | Issue: | Pt 2 | Abstract: | In the title compound, {(C(5)H(14)N(2))[Cd(2)Cl(6)]·H(2)O}(n), the asymmetric unit contains one piperazinediium cation, one [Cd(2)Cl(6)](2-) anion and a water mol-ecule. The coordination geometries of the two Cd(2+) cations are distorted octa-hedral. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride bridges, generating polymeric chains parallel to [010]. Neighbouring chains are connected by O-H⋯Cl hydrogen bonds involving the water mol-ecules, forming layers at z = n/2. The crystal packing is further stabilized by inter-molecular N-H⋯Cl and N-H⋯O hydrogen bonds, one of which is bifurcated. | URI: | https://hdl.handle.net/10316/109826 | ISSN: | 1600-5368 | DOI: | 10.1107/S1600536812001626 | Rights: | openAccess |
