The reaction of NdCl_3 with NaC_5Me_5 generates a novel complex (C_5Me_5)_2Nd(μ-Cl)_2Na(DME)_2 (1).Then (1) reacts with 1 mol ratio Na and a little methyl-naphthalene generating another novel complex(C_5Me_5)_2Nd(μ-OCH_3)_2Na(DME)_2 (2).Complex (1) belongs to orthorhombic crystal system,space groupPbn2_1 with a=1.2635(3) nm,b=1.6127(5) nm,c=1.6543(4J nm,V=3.371(2) nm~3,D_c=1.36 gcm~(-3) andZ=4.The central metal Nd is coordinated by two C_5Me5 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) nm~3,D_c=1.26 gcm~(-3) and Z=4,Twofive-membered ring centroids and two p-oxygens of OCH_3 form a distorted tetrahedron around the centralneodymium ion.
