	Subordination and Coordination in English-Arabic Translation
		In English, compound sentences (coordination) are used to express related thoughts which are more or less equal and carry approximately the same weight; that is, when both clauses of the sentence are offered as new information; they are usually equal both syntactically and semantically.
		al. maintain that coordination is used when ease of comprehension is sought, but also hold that a compound sentence, "especially with and, is vague in that it leaves the specific logical relationship to the interference of the speaker" (ibid.:1040-1).
		Another reason that adds to the difficulty of counting subordination and coordination instances in Arabic is the fact that some Arab writers tend to write very long sentences, some of which could be a paragraph long with one full stop at the end and so many commas in between.

	Coordination Compounds - Historical Development, Nomenclature, Stereoisomerism, Stereochemistry, Carbonyls and ...
		Carbonyl compounds and organometallic compounds are two groups of coordination compounds in which carbon atoms are bonded to the metal center.
		In all three compounds, the metal ion is in an approximately octahedral environment, its coordination number is 6, and bonded to it are the four nitrogen atoms of a planar porphyrin-like ring.
		The stability of a coordination compound depends on the nature of the ligands and the atomic number and oxidation state of the metal.

		The solution of the soluble coordination compound and the insoluble weak base anion exchange resin are contacted at a temperature and for a time to effect bonding of a desired amount of the coordination compound to the resin.
		The reaction of the coordination compound with the resin, which is a strong one, takes place initially at the outer surface of the resin particle and may gradually progress inward.
		Also, the metal compound moiety of the complex may be reduced to zero-valent metal by means of such reducing agents; depending on the catalyst complex subjected to this step, the resulting material may have the zero-valent metal disposed as a shell about the resin particle or completely penetrating the same.

	Chapter 20 Review
		A coordination compound is a compound in which a central metal atom or ion is attached to a group of surrounding molecules or ions by coordinate covalent bonds.
		The coordination number of a metal in a particular complex depends on the metal ion's size, the ion's charge and electron configuration, and on the size and shape of the ligands.
		Compounds with the same formula but a different arrangement of atoms are called isomers.

		The number of atoms to which an atom is bonded; in a coordination complex, the number of positions where ligands are attached to the central metal ion; in a ionic compound, the number of ions of opposite charge surrounding an ion.

		The final proof of a naturally occurring compound's structure is established by synthesizing the compound from simpler molecules by means of identifiable and reproducible reactions.
		A coordination compound or complex refers to the grouping that is formed when a metal ion or atom accepts a pair of electrons from a molecule or ion.
		Coordination number zero corresponds to an isolated atom; coordination number one occurs for very simple molecule combinations such as Ni-NN that are stable only in very cold matrices such as argon.
