The crystalline compounds Ti2(OiPr)8(NH2Pr)2, Ti2(OiPr)6(OEt)2[NH2(CH2)3Si(OiPr)3]2 and Ti2(OiPr)8[NH2(CH2)6NH2] were obtained by reaction of Ti(OiPr)4 with the corresponding amines. The molecular structures of the amine adducts are centrosymmetric dimers in which the titanium atoms are bridged by two OR groups. The amines are coordinated axially to the Ti2(µ-OR)2 ring and hydrogen-bonded to a neighboring propoxy ligand. In the case of the 1,6-diaminohexane derivative, this results in coordination polymers where the Ti2(OiPr)8 units are interconnected by the diamine.
