cze	FUSION OF NHC´S AND AMIDINATO-ALUMINUM CHEMISTRY. NORMAL OR ABNORMAL?	The propensity of highly electron-deficient aluminium(III) compounds to interact with such Lewis bases as amines, phosphines or donor solvents is one of the cornerstones of classical organometallic chemistry. The first unusual example of congested Lewis adducts built up from the N-Heterocyclic carbene as a σ-electron donating system and aluminium(III) species was reported by Arduengo1 in early 1990s. However, since then only little attention has been directed toward aluminium-carbene complexes and only a handful of examples of abnormal carbenes of main group metals2 and zinc3 are known. The direct synthesis and structure of normal vs. abnormal amidinato-aluminium N-heterocyclic carbenes supported by a series of theoretical calculations will be demonstrated.	carbene,aluminum, amidinate
