The format for this Volume follows on from the modifications made to
the structure of this journal series, which were introduced in Volume 34. The
Volume is split into two sections: Comprehensive reviews and critical reviews.
Comprehensive reviews of the organometallic chemistry of a wide range
of elements from across the periodic table are included in this Volume.
These articles cover the literature from 2006 and 2007. Contributions are
made by John G. Brennan and Andrea Sella, Joanna Haywood and Andrew
E. H. Wheatley, Felipe Garcı´a and Dominic S. Wright, Mark G. Humphrey
and Marie P. Cifuentes. One important highlight is the review of the
chemistry of Group 14 by Richard A. Layfield which focuses on develop￾ments of these elements in lower oxidation states such as the alkyne
analogues, e.g. RMMR (M = Si, Ge, Sn and Pb).
