N2  - Two substances with extended two-dimensional networks through hydrogen-bond cross linkages, namely, &#91;Co(4,4&#8242;-bpy)(H2O4&#93; (ClO4)2.(4,4&#8242;-bpy)2.2H2O and &#91;Zn(4,4&#8242;-bpy)(H2O)3(ClO4)&#93; (ClO4).(4,4&#8242;- bpy)1&#183;5.H2O, were synthesized, in EtOH/H2O solution. The cobalt complex crystallizes in the triclinic space group P-1 with a 9&#183;113(2), b 11&#183; 093(2), c 11&#183;394(2) &#197;, &#945; 64&#183;04(3), &#946; 70&#183;18(3), &#947; 66&#183;91(3)&#176;, V 932&#183;9(3) &#197;3. The crystal structure contains 4,4&#8242;-bpy-bridged linear polymeric &#91;Co(4,4&#8242;-bpy)(H2O)4&#93;n chains, where the cobalt(II) is coordinated in a slightly distorted octahedral environment by four water molecules (Co-O 2&#183;088(2)-2&#183;101(2) &#197;) at the equatorial positions and two nitrogen atoms of the bridging 4,4&#8242;-bpy ligands (Co&#8211;N 2&#183;149(2) &#197;) at the axial positions. The chains are interconnected into a two-dimensional rhombic network by double hydrogen-bond bridges of the type Co&#8211;H2O &#183; &#183; &#183; bpy &#183; &#183; &#183; H2O&#8211;Co. The zinc complex also crystallizes in the triclinic space group P-1 with a 9&#183;0230(11), b 11&#183;299(2), c 16&#183;397(2) &#197;, &#945; 74&#183;429(11), &#946; 83&#183;132(9), &#947; 70&#183;654(12)&#176;, V 1518&#183;5(3) &#197;3. The crystal structure contains 4,4&#8242;-bpy-bridged linear polymeric &#91;Zn(4,4&#8242;-bpy)(H2O)3(ClO4)&#93;n chains, where the zinc atom is coordinated in a distorted octahedral environment by two nitrogen atoms of the bridging 4,4&#8242;-bpy ligands (Z&#8211;N 2&#183;104(2)&#8211;2&#183;117(2) &#197;), three water molecules (Zn&#8211;O 2&#183;068(2)&#8211;2&#183;091(2) &#197;) and one monodentate ClO4- anion (Zn&#8211;O 2&#183;320(2) &#197;). The chains are interconnected into a rhombic network alternately by single or double hydrogen-bond bridges of the type Zn&#8211;H2O &#183; &#183; &#183; 4,4&#8242;-bpy &#183; &#183; &#183; H2O&#8211;Zn.
