Nomenclature, abbreviations and classification of clathrochelates

The nomenclature proposed by Melson and Busch [9, 20] for monomacrocyclic compounds is not applicable to clathrochelates since 

Symbols of the apical substituents in the capping fragments of sarcophaginates and sepulchrates. 

The ligand capten belongs to ligands of group II, but its properties are close to those of subgroup 1.1. 

The substituents at the carbon atoms in the apical positions and at the coordinated nitrogen atoms are denoted by placing the appropriate prefixes to framework symbol (Table 1). 

Complexes with type I.II ligands are usually referred to as boron (tin, germanium, silicon, antimony)-capped macrobicyclic dioximates (oximehydrazonates, azineoximates). Their abbreviated
