Fig. 8: Selected α-NLMOs from Np–β showing the three bonding modes with the p-orbitals of the sulfur atoms.
From: Non–linear bonding trends in maleonitrile-1,2–dithiolate complexes of the transuranium actinides

The NLMO in a represents the primary bonding orbitals while b and c represent minor and negligible contributions, respectively. Numbers in parentheses are percentages.
