The compound $[$Ni$($C$34$H$28$P$3)($C$5$H$4$NS$]($BPh$4)$ A has a formula mass

of $1022\mathrm{.}6$ g mol$-1.$ The complex crystallises from solution in methanol

$($CH$3$OH$)$ in the triclinic crystal system with a unit cell volume of

$2700\mathrm{.}23.$ The density of the crystals is $1\mathrm{.}34$ g cm$-3.$ Calculate the

mass of the unit cell contents $($in Daltons$),$ and deduce the number of

cation$-$anion pairs of the complex and the number of molecules of

solvent per unit cell.
