Nanotubes of LaS-TaS2 could be easily synthesized, while tubular structure of the LaS-NbS2 were found to be rather rare in the product. To understand this riddle, quaternary alloys of LaS-NbxTa(1-x)S2 with ascending Nb concentration were prepared herein in the form of nanotubes (and platelets). Not surprisingly, the concentration of these quaternary nanotubes shrank (and the relative density of platelets increased) with increasing Nb content in the precursor. The structure and chemical composition of such nanotubes was elucidated by electron microscopy. Conceivably, the TaS2 in the MLC compounds LnS-TaS2 (Ln = lanthanide atom) crystallizes in the 2H polytype. High resolution transmission electron microscopy showed however that, invariably, MLC nanotubes prepared from 80 at% Nb content in the precursor belonged to the 1T polytype. Raman spectroscopy of individual tubes revealed that up to 60 at% Nb, they obey the standard model of MLC, while higher Nb lead to large deviations, which are discussed in brief. The analysis indicated also that such nanotubes do not exhibit the pattern assigned to charge density wave transition so typical for binary 1T-TaS2. The prospect for revealing interesting quasi-1D behavior of such quaternary nanotubes is also briefly discussed. 000086119 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2016-81118-P$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2017-87579-R$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2016-79776-P 000086119 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000086119 590__ $$a10.159$$b2018 000086119 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b22 / 293 = 0.075$$c2018$$dQ1$$eT1 000086119 591__ $$aCHEMISTRY, PHYSICAL$$b17 / 148 = 0.115$$c2018$$dQ1$$eT1 000086119 592__ $$a4.224$$b2018 000086119 593__ $$aChemical Engineering (miscellaneous)$$c2018$$dQ1 000086119 593__ $$aMaterials Chemistry$$c2018$$dQ1 000086119 593__ $$aChemistry (miscellaneous)$$c2018$$dQ1 000086119 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000086119 700__ $$aSerra, M. 000086119 700__ $$aPopovitz-Biro, R. 000086119 700__ $$aPinkas, I. 000086119 700__ $$aHouben, L. 000086119 700__ $$aCalvino, J.J. 000086119 700__ $$aJoselevich, E. 000086119 700__ $$aTenne, R. 000086119 700__ $$0(orcid)0000-0002-2071-9093$$aArenal, R.$$uUniversidad de Zaragoza 000086119 700__ $$0(orcid)0000-0001-6152-6784$$aLajaunie, L. 000086119 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
