The compound C12H10Cl3N3O8Ru2 is made up of various elements. These elements include carbon, hydrogen, chlorine, nitrogen, oxygen and ruthenium. One of the features of the compound is that it has a formula weight of 632.72grams/ mole. This is the weight obtained by summing the atomic masses of the elements that make up the compound. This mass means that from every one mole of the compound, the total weight is about 632.72 grams. It can be observed that the mineral is heavy as compared to other compounds of the same nature.
The compound is joined together by covalent bonds. At room temperature, the compound is a solid due to its strong covalent bonds. It is due to this that the compound melts at a temperature of about 120 k. generally, the compound is made by strong covalent bonds that join the elements. Considering that the elements making the structure are non metals, the structure is formed by sharing of electrons and this is why covalent bonds are formed.
In the structure, ruthenium is the central atom. Ruthenium is a transition metal with oxidation state of 1, 2 and 6. It is able to form several co ordinate bonds through sharing of electrons to form a complex ring like structure. In the structure, ruthenium has oxidation number of 6. It is therefore able to form a chelating legands. The structure has a co ordination number six. This is due to the fact that ruthenium which is the central atom is surrounded by six atoms.
The distance from one bond to another keeps on changing depending on the elements that are involved in the formation of the bond. For example, the bond distance between nitrogen and carbon is far much longer as compared to the distance between hydrogen and carbon. The fact that the distance keeps on changing shows that the structure has weak regions and strong ones. However, the bonds are interconnected leading to formation of a strong structure. This is why the structure above is a solid in nature with a high melting point.
The angels formed by the bonds in the structure keeps on changing. This can be mainly attributed to the fact that different elements are involved in the formation of the bonds. Some of the angles are about 90 degrees while other bonds form angles that are greater than 90 degrees. In this case therefore, it is not possible to specify the specific angle that the bonds in the structure form.
The compound above possesses a triclinic crystal structure. This is usually a complex structure which has no symmetry. Generally, this structure has the least symmetry as compared to the other structures. In a triclinic crystal structure, the vectors that join the elements are of unequal length. This structure has no mirror plane. What this means is that the structure cannot be divided into two similar parts that are equal.
The compound also belongs to the pinacoidal class of triclinic crystal structure. This class has three forms of appearance. The first form is the pyramids. In this form, three crystallographic axes meet to form a pyramid shaped form. The other form of the pinacoidal class forms prisms and domes. In this face, two crystallographic axes meet together so that the form is made. The face formed in this case could be dome shaped or a prism. Finally, when there is only one crystallographic axis meeting, the form is known as pinacoids. Of all the other classes of the triclinic crystal structures, pinacoidal class has symmetry. From this feature, the structure above has no specific shape since different faces will reveal a different shape.
The above structure has about 19137 reflections. Reflections usually change the appearance of the structure from different points of view. The reflections by the various elements of the structure are what cause the change in the appearance of the structure. In addition, the structure has about 4787 reflections.
