“…Ring-substituted ligands of the phenanthroline and bipyridyl type have been shown to form monomeric and dimeric complexes with nickel(II) and manganese(II) halides, [1][2][3][4] though only one such nickel complex has so far been reported.5 When the halide, X, is Cl, chlorine-bridged dimers [MLX2]2, containing five-coordinated nickel or manganese,2 are formed.…”

Antischistosomal analogs of hycanthone. III. Structure of the 1:1 chloroform solvate of 8-chloro-2-[2-(diethylamino)ethyl]-2H-[1]benzothiopyrano[4,3,2-cd]indazole-5-methanol, C20H22ClN3OS.CHCl3

“…The structural role of this solvent is merely to occupy space in crystal lattices or to stabilize the compounds by forming weak H-bonds (van Soest & Peerdeman, 1970). In these structures, chloroform molecules were observed to have large thermal motion (Wilford, Smith & Powell, 1968;Preston & Kennard, 1969;Schaefer & Marsh, 1969;Park, Collins & Hoard, 1970;Lauher & Ibers, 1974;Wang, Huie & Schaefer, 1979), partially disordered configurations (Summerville, Cohen, Hatano & Scheidt, 1978;Johnson & Scheidt, 1978;Davis & Einstein, 1978), or both (Hall, Rae & Waters, 1967). In some cases, even the stoichiometric ratios of chloroform to compound were not precisely defined (Petterson, Birnbaum, Ferguson, Islam & Sime, 1968;Mason & Towl, 1970;Wang, Huie & Schaefer, 1979).…”
