Figure 2
The environment of the hypophosphite anion of [Ni(H2O)6](H2PO2)2 in relation to the hexaaquanickel(II) cations, viewed along b. Thick dashed lines indicate O—H⋯O—P hydrogen bonds and thin dashed lines indicate OW⋯H—P contacts. Displacement ellipsoids are plotted at the 50% probability level and H atoms are drawn as small spheres of arbitrary radii. |
