title: Synthesis and crystal structure of 4-(2-ammonio-eth-yl)morpholin-4-ium di-chlorido-diiodido-cadmate/chlorido-tri-iodido-cadmate (0.90/0.10).
abstract: The crystal structure of the title compound, (C6H16N2O)[CdCl1.90I2.10], a new organic-inorganic hybrid salt synthesized in the form of single crystals, consists of discrete statistically distributed di-chlorido-diiodido-cadmate/chlorido-tri-iodido-cadmate anions (occupancy ratio 0.90:0.10) and 4-(2-ammonio-eth-yl)morpholin-4-ium cations, [NH3(CH2)2NH(CH2)4O]2+. The cations are linked by inter-molecular N-H⋯O hydrogen bonds, forming corrugated chains extending parallel to thecaxis. The [CdCl1.90I2.10]2-tetra-halidocadmate anions lie between the chains to maximize the electrostatic inter-actions and are connected with the organic cationsviaN-H⋯Cl and C-H⋯Cl(I) hydrogen bonds developing in theabplane and leading to the formation of a three-dimensional network structure. The tetra-coordinate CdIIatom has a distorted tetra-hedral conformation, with a τ4index of 0.87.
