Historically, coordination compounds have been depicted in various ways.
According to the Graphical Representation Standards for Chemical Structure Diagrams (IUPAC Recommendations 2008), bonds representing coordination from one atom to a single other atom should be represented as normal plain single bonds. The use of dative bonds (i.e. arrows pointing to ...

Yes there are more carbonylate ions than metal carbonyl cations, but the latter do exist. A salt $\ce{[Mn(CO)6^+][BF4^-]•SO2}$ has been synthesized in a superacid medium.
Metal carbonyl cations are often disfavored because they have to contend with counterions that are anions, which may compete with the carbon monoxide ligands. Such a competition is ...

I believe this website will be of use to you
http://molview.org/
It appears to take names, formulas, smiles etc. If the name/formula/smile ID pops up in the search bar, it will draw it for you. Its database seems quite large, I use it for some pretty big drug molecules.
It draws 2D and 3D images, and it also does single/double/triple bonds.

To determine what orbitals do, it is often a good idea to look at the symmetry group as it can provide a rough overview over what can (symmetry-allowed) and cannot (symmetry-forbidden) happen. In the case of a quadruple bond such as $\ce{[Re2Cl4]^2-}$, we can approximate the rhenium(III) centres as being close to $C_\mathrm{4,v}$. A quick glance at the ...
