Description
Summary:The single crystal X-ray structure of indodicarbocyanine dye has been determined at room temperature and its chemical structure confirmed. A unit cell consists of four organic cations, four iodide anions and four H 2O molecules; H 2O molecules are involved into the unit cell during the crystallization. Hydrogen bond interaction probably exists between the iodide anion and a H 2O molecule. The N-atoms are in a cis-type arrangement with respect to the methine chain, and the distributions of bond lengths indicate extended delocation of π-electrons. The molecules are stacked face-to-face to form a column along the b axis direction, and some dimerization is observed.
