Two complexes,[Cu(salpn) ]·NH( CH_3)_2( 1) and [Ni( salpn)·H_2O]( 2)( H_2salpn= N,N-bis( salicylidene)-propane-1,3-diamine) were characterized by IR,element analysis and single crystal X-ray diffraction analysis. Crystal data for complex 1 : monoclinic,P2_1/ C,a = 1.0974 × 10^(-7)cm,b = 1.4806 × 10^(-7)cm,c = 1.0315 × 10^(-7)cm,β = 94.43( 3) °. The Cu( II)ion in complex 1 is four coordinated with distorted square planar coordination geometry. The crystal structure of complex 1 consists of [Cu( salpn) ] coordination complex and a guest molecule NH( CH_3)_2that can act as both H-bonding donor and acceptor and plays an important role in constructing supramolecular architecture. Crystal structure data for complex 2 : orthorhombic,Pnma,a = 8.6763× 10^(-8)cm,b = 2.4145 × 10^(-7)cm,c = 7.5388 × 10^(-8)cm. The Ni( II) ion in complex 2 is fivecoordinated with a butterfly coordination geometry. The coordinated water molecule plays a key role in hydrogen-bonded networks.
