This book introduces the concept of crystallographic non-
rigidity and asymmetry of the transition elements as central
atoms organometallic compounds. This intrinsic behavior of
central atoms in condensed matter is quantified by applying
statistical approach. Averaging of extrinsic factors in
crystal structures is tested by using variance analysis.
Introductionof the above mentioned concept and applications
of variance analysis as an approximation for considering
factors influencing properties of central atomin the
crystal is original and new.
