Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the subject complex suitable for the coordination polymerization of various monomers by reacting a mononuclear metal complex in the presence of hydrogen under a specific pressure and at a specific temperature. SOLUTION: A mononuclear metal complex expressed by formula I [M is Sc, Y, La, etc.; R is H, a halogen, a 1-20C alkyl or the like; Z is SiR'2(R' is a 1-20C alkyl or the like), O or the like; (m) is 1, 2; X is O, S or the like; L is a low molecular weight Lewis base; and (n) is 0 or l] is reacted in the presence of hydrogen, at 1.5-100 bar pressure and 0-100 deg.C temperature, preferably in an inactive solvent such as n-pentane or the likes to obtain a complex expressed by formula II, e.g. bis[tetramethylcyclopentadienyl(tert-butylamide) dimethylsilylyttrium hydride]. The side complex is useful as a catalyst for (co)polymerizing polar monomers.
