摘 要:<正> The reaction of NdCl3 with NaC5Me5 generates a novel complex (C5Me5)2Nd(μ-Cl)2Na(DME)2 (1).Then (1) reacts with 1 mol ratio Na and a little methyl-naphthalene generating another novel complex(C5Me5)2Nd(μ-OCH3)2Na(DME)2 (2).Complex (1) belongs to orthorhombic crystal system,space groupPbn21 with a=1.2635(3) nm,b=1.6127(5) nm,c=1.6543(4J nm,V=3.371(2) nm3,Dc=1.36 gcm-3 andZ=4.The central metal Nd is coordinated by two C5Me5 ring centroids and two μ-chlorine atoms forming adistorted tetrahedron.The crystal of complex (2) is monoclinic,space group C2/n with a=1.7482(5) nm,b=1.3260(4) nm,c=1.6406(7) nm,β=109.39(3)°,V=3.5874(1) nm3,Dc=1.26 gcm-3 and Z=4,Twofive-membered ring centroids and two p-oxygens of OCH3 form a distorted tetrahedron around the centralneodymium ion.
