ChemInform Abstract: The Crystal Structures of Chloro Mercury(II) Salts Found for Some CrN3+ 6 Cations and Their Cr-N Bond-Ruptured Hydrolysis Products.
Abstract
Crystal structures are determined for chloromercury(II) salts formed from (Cr(en)3)Cl3 and isomeric forms of (Cr(dien)2)3+ (dien: NH2-(CH2)2-NH-(CH2)2-NH2) on crystallization from HCl containing excess HgCl2.
ChemInform Abstract
Crystal structures are determined for chloromercury(II) salts formed from (Cr(en)3)Cl3 and isomeric forms of (Cr(dien)2)3+ (dien: NH2-(CH2)2-NH-(CH2)2-NH2) on crystallization from HCl containing excess HgCl2. The products (II) and (VI) are formed at long reaction times. The choice of anion is critical for obtaining single crystals suitable for X-ray structure analyses. The empirical stoichiometry (Hg2Cl7)3+ consists of different anions in the salts (IV)-(VI). Crystal data are: (I) (P1, Z=2), (II) and (VI) (P21/c, Z=4), (III) (P2/n, Z=2), (IV) (P1, Z=4) and (V) (Pbca, Z = 8). Ring conformations for the chelates are reported.
