What does the fact that no more than two forms of any MA 4 B 2 complex were known tell you about the three-dimensional structures of these complexes? Ammonia was first detected in interstellar space inbased on microwave emissions from the direction of the galactic core. Moreover, in the electron dot formulas that we have written above, the boron has only six electrons in its valence shell. Ammonia is a colourless gas with a sharp, penetrating odour. Ammonia can also be used to make compounds in reactions which are not specifically named. The study of interstellar ammonia has been important to a number of areas of research in the last few decades.

    Ammonia engines or ammonia motors, using ammonia as a working fluidhave been proposed and occasionally used. Ammonia and ammonium salts are also found in small quantities in rainwater, whereas ammonium chloride sal ammoniacand ammonium sulfate are found in volcanic districts; crystals of ammonium bicarbonate have been found in Ronak guano.

    In general, the differences in energy between different arrangements of ligands are greatest for complexes with low coordination numbers and decrease as the coordination number increases. Practice Problem 2: Calculate the charge on the transition-metal ion in the following complexes.

      This relatively uncommon coordination number is generally encountered for only large metals such as the second- and third-row transition metals, lanthanides, and actinides. It is thought that the low-temperature conditions allow this molecule to survive and accumulate.
