• A tetranuclear Li2Cr2 acetylide precursor complex, [Li（Tp）crm（c=CSiMe3）2（/,t3-pz）]2· （n-pentane）2 （Tp = hydridotris（pyra- zolyl）borate, pz = pyrazolate） （1） has been synthesized and characterized. The X-ray structure analysis shows that the complex contains a Li2Cr2 core bridged by two ,u3-pyrazolates. The magnetic data exhibit the existence of weak antiferromagnetic in- teraction in the cluster.
