The preparations of the N , N ‐dialkylcarbamato complexes with analytical formulae [Ln(O 2 CNR 2 ) 3 ] (Ln = Pr, Nd, Eu, Gd, Ho, Er, Yb, Lu, R = i Pr; Ln = Nd, Eu, Gd, R = Bu; Ln = Nd, R = Et), using [LnCl 3 (ether) x ] (ether = THF or dimethoxyethane, DME), NHR 2 , and CO 2 are reported. X‐ray diffraction of the diisopropylcarbamato derivatives, including a reinvestigation of [Yb 4 (O 2 CN i Pr 2 ) 12 ], showed these complexes to be tetranuclear and isotypical over a range of 12 atomic numbers. The lanthanide contraction has been evaluated based on the lengths of four different types of Ln−O bond. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
