A novel entangled architecture [Co(1.5)(bpmp)(Hcda)(cda)(H(2)O)] (1) based on 4(4)-sql subunits, showing an interesting 2D → 3D inclined polycatenation structure feature, is reported. Magnetic investigation shows that compound 1 exhibits coexistence of paramagnetism and canted antiferromagnetism with Tc of 48 K.
