eng	STRUCTURAL OVERVIEW OF MONODEPROTONATED GUANIDINE COORDINATION VERSATILITY TO MAIN GROUP ELEMENTS	New classes of ligands are becoming a centre of interest in the coordination chemistry of main group element compounds recently. N-containing ligands represented by amidinates, guanidinates and β-diketiminates are promising thanks to their hybrid σ- and π-bonding opportunities (Fig. 1).1,2 A series of fourteen guanidinate coordination compounds was synthesized containing lithium, magnesium, zinc, aluminium, tin, phosphorus, and gallium by electrophilic substitution of the ligand, or via subsequent reaction with previously prepared complexes. This proves that monodeprotonated guanidine ligand can accommodate all kinds of steric and mainly electronic needs demanded by the variety of central atoms by forming four-, five-, or six-membered diazametallacycles.3 Diverse structural motives and trends across the series of complexes will be discussed in detail, including crystal structure and constitution, interatomic distances, bond and dihedral angles, and coordination sphere arrangement.
