Classic scorpions

Co(Bpph2) (pz )Bpph2 ]. 2C6H14 (Fig. 4.11) have been reported. The scorpionate ligands are coordinated in the classical k3-coordination mode in all complexes. In the nitrate derivative, the coordination sphere is completed by three oxygen donor atoms from NO3 and THF whereas in the heteroleptic complex, Bpph2 acts as a k3-A 2, H-donor.64... 

Examples of fatty acid-derived defensive compounds are widespread among arthropods. In the simplest cases, long-chain fatty acids themselves have been shown to serve as repellents that deter predators such as ants. °° A classic example is the defensive secretion of the whip scorpion, Mastigoproctus giganteus, which contains an aqueous mixture of acetic and caprylic acids. More recent examples include the mayolenes... 

Arthropod-derived toxins are also among the list of classical examples of toxins used to probe biochemical processes. Scorpion toxins have been important in the experimental determination of the spacial arrangement of residues on the potassium channel (11), and also in the inference of properties of its quaternary structure (12). A scorpion toxin was used as a tool in the first isolation of a specific component of an insect sodium channel (13). Spider toxins have been similarly useful in characterization of calcium channels (14).
