I am trying to find a linear molecule that is a liquid at room temperature and pressure.

Do you know of any?

By linear I mean that all the bonds are co-linear (ie. simple alkane carbon chains don't count). Non hazardous materials are preferable.

    $\begingroup$ Well, that is a typical example of an xy problem: You are asking about y without the context of x. If you had described the purpose you want it for, and possibly given some tighter criteria of what you are looking for, this would be a less broad question, be of more use for further guests, possibly have a wider audience, and will most likely have been perceived better. I generally agree with Mithoron about it being too broad. $\endgroup$ – Martin - マーチン May 9 '20 at 15:18

    $\begingroup$ You cannot delete it; and I never even implied that this was the way forward. I would encourage you to improve the question by editing it. You might be surprised to find even more answers eventually, and that would be a great service to future users of this site, just liked you would have found it helpful if someone had asked a question similar to this. $\endgroup$ – Martin - マーチン May 9 '20 at 16:00

Technically liquid, but close to the boiling point and a bit nasty to work with, is carbon disulfide. It melts at about -112°C and boils at +46°C.
