Synthesis and Crystal Structure of a Dicyanamide-bridged One-dimensional Gadolinium(III) Complex [Gd(dca)_3(phen)_2(H_2O)]_n

1 INTRODUCTION Dicyanamide is a versatile bridging ligand linking two or more metal ions with three nitrogen donor atoms[1～4]. The varieties of its coordination modes provide multifarious chances for designing new com- plexes with novel structures as well as interesting properties. Firstly, the complexes formulated as [M- (dca)2]n (M = Mn, Fe, Co, Ni, Cu, Cr)[5～9] mostly with 2D and 3D networks have been synthesized, and they usually exhibit high ordering temperatures. Afterwards, t…     

Synthesis and Crystal Structure of [MoOS_3Cu_3I(dmpzm)_2]·2(MeCN)_(0.5) (dmpzm=Bis(3,5-dimethylpyrazolyl)methane)

1 INTRODUCTION The synthesis of molybdenum-copper-sulfur clus- ters from the preformed clusters with certain nitro- gen donor ligands remains attractive due to their rich chemistry and electro/photonic properties[1~6]. How- ever, the third-order nonlinear optical performances of these Mo/Cu/S clusters have been limited due to their relatively low solubility in common organic solvents[5]. One possible way to tackle this problem is to introduce bulky organic ligands into the cluster framew…
