The synthesis and crystal structure analysis of the ditopic p-phenylene-bridged bis(pyrazol-1-yl)borate [[p-C6H4-(Bpz(2)tBu)(2)]Li-2] (LLi2; pz = pyrazol-1-yl) is described. A salt metathesis reaction between LLi2 and MnCl2 in THF leads to the dinuclear complex [L[Mn(THF)](2)(mu-Cl)(2)] featuring a central diamond Mn-II-(mu-Cl)(2)-Mn-II core (X-ray crystal structure analysis). Treatment of LLi2 With 2 equiv of [Ti(NMe2)(3)Cl] gives the dinuclear titanium compound [L[Ti(NMe2)(3)](2)]. Upon reaction of LLi2 With [Ti(NMe2)(2)Cl-2] and water, the mu-oxo-bridged dititanium species [L[Ti(NMe2)Cl](2)(mu-O)] is obtained in excellent yield (X-ray crystal structure analysis).
