PROBLEM TO BE SOLVED: To provide a transition metal compound catalyst that makes it possible to synthesize an olefin polymer that is soft and has improved catalytic activity and reduced stereoregularity, and a method for producing an olefin polymer.SOLUTION: The present invention provides a compound represented by formula (IV) (X is a σ-binding or π-binding ligand; Y is a Lewis base; Y may be crosslinked to other Y and X; q is an integer of 1-5 and [(valence of M)-2]; r is an integer of 0-3; Rand Rindependently represent H or halogen, alkyl or the like; R-Rare alkyl groups. M is metal elements of groups 3-10 or lanthanoid series in the periodic table; A-Aindependently represent a crosslinking group composed of group 14 (C, Si, Ge, Sn)).SELECTED DRAWING: None 【課題】触媒活性が高く、より立体規則性の低い軟質なオレフィン系重合体を合成し得る遷移金属化合物触媒とオレフィン系重合体の製造方法の提供。【解決手段】式（ＩＶ）で表される化合物。（Ｘはσ結合性又はπ結合性の配位子；Ｙはルイス塩基；Ｙは他のＹやＸと架橋していてもよい；ｑは１〜５の整数で［（Ｍの原子価）−２］；ｒは０〜３の整数；Ｒ１及びＲ２は夫々独立にＨ又ハロゲン、アルキル等；Ｒ３〜Ｒ１０はアルキル基。Ｍは周期表第３〜１０族又はランタノイド系列の金属元素；Ａ１〜Ａ４は夫々独立に第１４族（Ｃ、Ｓｉ、Ｇｅ、Ｓｎ）からなる架橋基）【選択図】なし
