In the title complex, [CuCl2(C6H7N)2(CH3OH)], the copper atom is five-coordinated by two nitrogen atoms of 2-methylpyridine ligands, two chloro ligands and an oxygen atom of the methanol molecule, being in a tetragonal–pyramidal environment with N and Cl atoms forming the basal plane. In the crystal, complex molecules related by the twofold rotation axis are joined into dimeric units by pairs of O—H...Cl hydrogen bonds. These dimeric units are assembled through C—H...Cl interactions into layers parallel to (001).

“…The Cd±ligand bond distances can be compared with those found in Cd complexes retrieved from the Cambridge Structural Database (CSD; Allen, 2002) and Inorganic Crystal Structure Database (ICSD, 2005). Out of a total of 23 structures containing [CdCl 6 ] 4À complexes, only three show the presence of isolated anions (Beck & Milius, 1986;Veal & Hodgson 1972;Wagner et al, 1996); the CdÐCl distances in these compounds agree well with those reported in Table 1 for (I), ranging from 2.53 to 2.68 A Ê . The mean value of 2.72 (3) A Ê for the CdÐSCN bond length, calculated for a sample containing 68 entries (from the CSD), compares well with the length of 2.696 (1) A Ê reported in Table 1.…”

In the title complex salt, tetrakis[hexaamminecobalt(III)] hexachlorocadmate(II) bis[aquatetrachlorothiocyanatocadmate(II)] dichloride dihydrate, the discrete ions, i.e. [Co(NH3)6]3+, Cl-, [CdCl6]4- (located on an inversion centre) and [CdCl4(SCN)(H2O)]3-, together with cocrystallized water molecules, are assembled by means of a network of hydrogen-bonding interactions. This is the first X-ray structure determination of a hexaamminecobalt(III) salt with two different complex chlorocadmium anions.

Crystals of [Co(C2H8Nz) Werner (1912) demonstrated the optical activity and octahedral nature of complexes of cobalt and ethylenediamine by using the crystallization of (+)-tartrate salts to separate the enantiomers. One of the salts he isolated was (+)-tris(ethylenediamine)cobalt(III) chloride (+)-tartrate pentahydrate. We first became interested in this material when it was the subject of an experiment devised by McClain (1972) for the elementary chemistry laboratory course at Berkeley. We determined the crystal structure because lack of knowledge of it was an embarrassment in explanations to students. Later we realized that this salt is suitable for measuring anomalous-scattering effects of cobalt and chlorine by a method described by Templeton & Templeton (1978).In this paper we report the crystal structure and some measurements of scattering of Mo Ka and Cu Ka radiation. This study provides a foundation for some similar experiments with synchrotron radiation near the Co K absorption edge which will be described elsewhere. mm -1) was made using the program HORSE (Hamilton, 1969) that approximates the crystal as an array of points (480 in this case). The extreme correction factors were 1.15 and 1.22. Before the final refinement each structure factor was multiplied by 1.0 + 1.8 x 10-7/, an empirical correction for extinction which was 1.18 for the strongest reflection, i 11, I is the uncorrected observed intensity. For 188 reflections the intensity was less than a estimated from counting statistics, and these were given zero weight in the structure refinement. The remaining 7688 reflections, including both members of each Bijvoet pair, were assigned weights w = [a(F)]-2; o(F) was derived from cr(F 2) = [S 2 + (jgF2)2] 1/2, where S 2 is the variance due to counting statistics and p = 0.03. ExperimentalAnother crystal, 0.102 x 0.084 x 0.110 mm, was used to measure diffraction intensities with CuKa radiation. The technique was similar except that scan widths were 1.5 °, plus al-a 2 splitting, the scan speed was 2 ° min -1, and backgrounds were measured at each end of the scan. Measurements of 3434 reflections, including both members of each Bijvoet pair, yielded
